WDM: an energy-efficient multi-hop routing algorithm for wireless sensor networks

As a new technique, one characteristic of wireless sensor networks (WSNs) is their limited system lifetime. Therefore, it is more important to save energy and proportion energy consumption. This paper presents a weight-directed based multi-hop routing algorithm for WSNs. This algorithm can transfer data quickly to goal sensor node using the directional information and RWVs (route weight value) of sensor nodes as well as balance energy consumption of all sensor nodes. Detailed simulations of sensor network environments indicate that this algorithm improves energy efficiency and proportions energy consumption of all sensor nodes to extend network system lifetime, and routes data quickly in comparison to the flooding algorithm.
