Power-Efficient Reliable Routing Protocol for Mobile Ad-Hoc Networks
IEICE Transactions on Communications, 2005Co-Authors: Kyoung Jin Kim, Sang-jo YooAbstract:Since mobile ad-hoc networks have certain constraints, including Power shortages, an unstable wireless environment, and node mobility, more Power-Efficient and reliable routing protocols are needed. Accordingly, this paper propose a new routing protocol, PERRA (Power Efficient Reliable Routing protocol for mobile Ad-hoc networks), that includes the advantages of on-demand protocols, while also providing Power- Efficient and reliable packet transmission. PERRA uses a new cost function to select the optimum path based on considering the minimum residual energy of the nodes on a path, the total energy consumed by a path to transmit and process a packet, and the path's stability in accordance with the node mobility. As a result, the proposed method increases the Power efficiency, decreases the route-reconstructions due to residual Power shortages and node mobility, and provides effective route maintenance mechanisms. The performance of PERRA is evaluated by simulations under various conditions.

A novel Power-Efficient broadcast routing algorithm exploiting broadcast efficiency
2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003Co-Authors: Intae Kang, Radha PoovendranAbstract:It has been shown that the problem of finding a broadcast routing tree with minimum total transmit Power is NP-hard. Hence, developing a heuristic Power-Efficient algorithm is crucial. The seminal work in this area is the well-known broadcast incremental Power (BIP) algorithm with a recent addition called embedded wireless multicast advantage (EWMA) algorithm. In this paper, we present yet another novel Power-Efficient algorithm for broadcast routing tree construction called greedy perimeter broadcast efficiency (GPBE) algorithm. We also compare the performance of these algorithms.

GLOBECOM - A comparison of Power-Efficient broadcast routing algorithms
GLOBECOM '03. IEEE Global Telecommunications Conference (IEEE Cat. No.03CH37489), 1Co-Authors: I. Kang, Radha PoovendranAbstract:Following the seminal work of Wieselthier et al. on Power-Efficient broadcast routing, a novel technique called embedded wireless multicast advantage (EWMA) was proposed to further reduce the total transmit Power of a broadcast routing tree. In our previous work, we showed that when the network lifetime is defined as the time for the first node failure due to battery depletion, the total transmit Power is not the only measure of Power-efficiency. We proved that either maximum transmit Power or link longevity plays a crucial role in extending the network lifetime. In this paper, we compare the performance of four known Power-Efficient algorithms (and their variants) not only in terms of the total transmit Power but also in terms of other performance measures such as static network lifetime, total receive and interference Power, and maximum and average hop count which have direct impacts on physical, link, and MAC layers and on end-to-end network delay.

A scalable, Power-Efficient broadcast algorithm for wireless networks
Wireless Networks, 2006Co-Authors: Jennifer C. HouAbstract:Scalability and Power-efficiency are two of the most important design challenges in wireless ad hoc networks. In this paper, we present a scalable, Power-Efficient broadcast algorithm for wireless ad hoc networks. We first investigate the trade-off between (i) reaching more nodes in a single hop using higher transmission Power and (ii) reaching fewer nodes using lower transmission Power and relaying messages through multiple hops. Our analysis indicates that multi-hop broadcast is more Power-Efficient if α ≥ 2.2, where α is the path loss exponent in the Power consumption model P(r, α) = c0 ċ rα + c1. Based on the analysis, we then propose Broadcast over Local Spanning Subgraph (BLSS). In BLSS, an underlying topology is first constructed by a localized topology control algorithm, Fault-Tolerant Local Spanning Subgraph (FLSS). FLSS can preserve k- connectivity of the network, where the value of k determines the degree of fault tolerance. Broadcast messages are then simply relayed through the derived topology in a constrained flooding fashion. BLSS is fully localized, scalable, Power-Efficient, and fault-tolerant. Simulation results show that the performance of BLSS is comparable to that of centralized algorithms.

QSHINE - BLMST: a scalable, Power-Efficient broadcast algorithm for wireless networks
First International Conference on Quality of Service in Heterogeneous Wired Wireless Networks, 1Co-Authors: Jennifer C. HouAbstract:The Power-Efficient broadcast for multi-hop wireless networks is discussed in this paper. We first investigate the trade-off between (i) using larger transmission Power to reach more nodes in one hop and (ii) using smaller Power and relaying broadcast messages through multiple hops. Analysis indicates that multi-hop broadcast is more Power-Efficient if /spl alpha/ /spl ges/ 2.2, where the Power consumption model is P(r, /spl alpha/) = c/sub 0/ /spl middot/ r/sup /spl alpha// + c/sub 1/. Based on the analysis, we propose broadcast on local minimum spanning tree (BLMST). An underlying topology is first derived using local minimum spanning tree (LMST), a localized topology control algorithm. Broadcast messages are then simply relayed through the derived topology in a constrained flooding fashion. BLMST is fully localized, scalable, and Power-Efficient. Simulation results show that the performance of BLMST is comparable to that of existing centralized algorithms.

A Power-Efficient MAC Protocol for WBAN
The Journal of The Korea Institute of Intelligent Transport Systems, 2009Co-Authors: Kyung Sup Kwak, Sana Ullah, Daehan Kwak, Cheolhyo Lee, Hyung-soo LeeAbstract:A key challenge for Wireless Body Area Network (WBAN) is to maximize the network lifetime with Power-Efficient and flexible duty cycling techniques on energy-constraint sensor nodes. In this paper, we propose a novel Power-Efficient MAC protocol for WBAN that accommodates normal, emergency, and on-demand traffic in a reliable manner. This protocol supports two wakeup mechanisms, a traffic-based wakeup mechanism, which accommodates normal traffic by exploiting the node's traffic patterns, and a wakeup radio mechanism, which accommodates emergency and on-demand traffic by using a wakeup radio. It can be seen that the proposed protocol not only improves the lifetime of WBAN but also provides a reliable method to handle sporadic events. Simulation results show that the proposed protocol outperforms WiseMAC in terms of low-Power consumption and delay.
