An Energy-Balanced Routing Scheme Based on Prim Algorithm in Heterogeneous Wireless Sensor Networks
In wireless sensor network, there are many hurdles takes place in providing quality of service routing to a desired level. The majority of routing protocols in wireless sensor networks concentrates on energy efficiency as a prime factor. Developing an energy–efficient routing protocol has a significant impact on the overall lifetime and stability of the sensor network. In this paper, we have considered three types of sensor nodes. Some fraction of the sensor nodes are equipped with the additional energy resources than the other nodes. We have assumed that all the sensor nodes are uniformly distributed. In the Heterogeneous WSN, we proposed an energy efficient cluster head election protocol and using the improved Prim’s algorithm to construct an inter-cluster routing. Simulation results show out method is more efficient to reduce and balance energy consumption and hence prolong the lifetime of WSN.
