Rendezvous Based Adaptive Path Construction for Mobile Sink in WSNs Using Fuzzy Logic

In this paper, an adaptive path construction approach for Mobile Sink (MS) in wireless sensor networks (WSNs) data gathering has been proposed. The is constructed based on selecting Rendezvous Points (RPs) the sensing field where MS stops order to collect data. Compared with most existing RP-based schemes, which rely fixed RPs construct these points will stay during whole network lifetime, we propose locations of are dynamically updated using a Fuzzy Inference System (FIS). proposed FIS, named Fuzzy_RPs, three inputs and one output. are: remaining energy nodes, transmission distance between number surrounding neighbors each node. output FIS weight value node generated previous parameters and, thus, RP its new location accordingly. Simulation results have shown that extends lifetime compared another uses RPs. For example, terms first dead as metric when deployed nodes changes from 150 300, improvement ranges 48.3% 83.76% achieved related
