Abstract

Reducing energy consumption and increasing network lifetime are the major concerns in Wireless Sensor Network (WSN). Increase in network lifetime reduces the frequency of recharging and replacing batteries of the sensor node. The key factors influencing energy consumption are distance and number of bits transmitted inside the network. The problem of energy hole and hotspot inside the network make neighbouring nodes unusable even if the node is efficient for data transmission. Energy Efficient Energy Hole Repelling (EEEHR) routing algorithm is developed to solve the problem. Smaller clusters are formed near the sink and clusters of larger size are made with nodes far from the sink. This methodology promotes equal sharing of load repelling energy hole and hotspot issues. The opportunity of being a Cluster Head (CH) is given to a node with high residual energy, very low intra cluster distance in case of nodes far away from the sink and very low CH to sink distance for the nodes one hop from the sink. The proposed algorithm is compared with LEACH, LEACH-C and SEP routing protocol to prove its novel working. The proposed EEEHR routing algorithm provides improved lifetime, throughput and less packet drop. The proposed algorithm also reduces energy hole and hotspot problem in the network.

5 Conclusion

Energy hole and hotspot inside the network creates additional load to the nodes making the hole larger. The problem is solved through proper clustering mechanism in the network. The proposed algorithm provides better clustering and repels the energy hole when compared to other LEACH, LEACH-C and SEP algorithm. The clustering mechanism is also with respect to the location of the sink. The proposed algorithm provides better lifetime and throughput to the network. The increase in the number of cluster near the sink also promotes reduced time delay making effective solution to the delay problem. The EEEHR algorithm serves to be a novel solution for the energy problem currently faced by the network.
