Wireless Sensor Networks (WSNs) have included one of the major challenges as energy efficiency.The optimal routing is the better solution for tackling the energy-efficiency problem as the energy is consumed with massive amount by the communication of a network.The clustering technique is the reliable data gathering algorithm for achieving energy-efficiency.The data transmit to the cluster head (CH) by each node that belonging to the cluster for clustered networks.The data transmission towards the BS or SINK is occurred once all data is received by CH from all member nodes.In multi-hop environments, the data transmission happens via other cluster-heads.It leads to the earlier death of CHs that are nearer to the SINK because of the heavy inter-cluster relay, i.e. called as hot-spot problem.The existing methods of unequal clustering approaches have been used to resolve this issue.The algorithms generate the clusters with smaller sizes while approaching towards the sink for reducing the intra-cluster relay.These algorithms didn't consider the hotspot problem very effectively.Therefore, in this work, we introduce a multi-objective fuzzy logic based multi-path routing solution (MOFL-MPR) to address the above said problem.The popular clustering algorithms have been evaluated the performance results and the MOFL-MPR is outperformed the existing algorithms based on the obtained experimental results in terms of stable CH selection, energy efficiency and better data delivery.
