A Wireless Sensor Networks routing algorithm optimized based on potential field

Motivated by characteristics of the data transmission in the Wireless Sensor Networks (WSN), this paper proposed a WSN routing algorithm optimized based on the concept of potential field in the physics. In routing selecting the proposed algorithm synthetically considers the factors of hops, reserving energy of node and its neighbours. Utilizing various parameter and factors, the algorithm constructs different potential fields, which move the data packets along the direction of the largest force. Therefore, this algorithm lets the energy consumption tending to keep at same level, avoids selecting the node with larger residual energy instead of lower power of its neighbours, and prolongs the lifetime of networks. This new algorithm has lower complexity to carry out at nodes, and experimental results illustrate that it has a better performance on balancing energy consumption and prolonging lifetime of WSN.
