ADHOP: an Energy Aware Routing Algorithm for Mobile Wireless Sensor Networks

Sensor nodes usually propagate data packets in a multihop fashion. However, in the most of routing protocols, the optimal routes are likely to be used for the following transmissions. As a result, the optimal routes tend to accelerate the energy depletion of nodes, especially in low-power networks, which are noisy and error-prone. ADHOP is a low overhead routing algorithm which can adapt to dynamic topologies. Such protocol is designed to use metrics as heuristic information to support routing decisions according to the network needs, such as distance, latency, residual energy, and/or signal strength. Our approach aims at using residual energy as a metric in ADHOP to distribute the network traffic load, thus balancing the energy consumption among nodes without compromising communication. Such method also allows us to achieve a routing algorithm powerful enough to reduce the energy consumption per delivered data in high data loss scenarios.
