Data Gathering Based on Nodes’ Credit in Wireless Sensor Network

For data gathering in wireless sensor networks, sensors extract useful information from environment; this information has to be routed through several intermediate nodes to reach the destination. How information can effectively disseminate to the destination is one of the most important tasks in sensor networks. Problem arises when intermediate nodes fail to forward incoming packets. Due to limited power and slow processor in each node, algorithms of sensor networks must be designed carefully. Directed Diffusion (DD) is a typical data-centric algorithm which has been used to provide efficient data transmission. We enhance this algorithm based on nodes’ credit by using five factors. Simulation results show that our proposed algorithm is more energy efficient and reliable than DD and has the ability of traffic load distribution.
