This paper proposes a distributed energy-efficient routing algorithm for mobile Ad Hoc networks (MANETs). We adopt the cross-layer design paradigm. The distance from the source node to the destination node is estimated based on the received signal strength indication (RSSI) of the packets and is used to adaptively adjust the backoff time of the MAC layer. A distance threshold and a packet count threshold...
Information dissemination in disaster scenarios requires timely and energy-efficient communication in intermittently connected networks. When the existing infrastructure is damaged or overloaded, we suggest the use of a manycast algorithm that runs over a wireless mobile ad hoc network, and overcomes partitions using a store-and-forward mechanism. This paper presents a random walk gossip protocol...
Random walk is one of the widely used techniques for information discovery in unstructured networks like ad hoc wireless networks (AWNs) and wireless sensor networks (WSNs). In a random walk, instead of taking all steps uniform randomly, our idea is to modify random walk to take some level biased steps to improve its energy efficiency and latency which are important design parameters in WSNs. The...
The LEACH algorithm for selecting cluster heads is a probabilistic method which produces clusters with a large variation of link distances and uneven energy consumption during the data transmission phase. To address this issue, a RF signal strength algorithm based on link quality is presented. Using a competitive distributed algorithm, nodes attempt to reduce the overall energy required for transmission...
