A Fuzzy Logic based Joint Intra-cluster and Inter-cluster Multi-hop Data Dissemination Approach in Large Scale WSNs
2015
Improving network lifetime in wireless sensor networks (WSNs) is a major concern in the recent years. Currently, various approaches have been proposed with having many concepts in this context. The main problem seems in the recent proposed approaches is that these approaches use direct communication among nodes with the rotation of cluster heads (CHs) periods to distribute energy consumption. However, energy saving mechanisms based only on metric related to nodes' residual power cannot be directly applied to find stable CHs. The reason is that a sensor node or a CH having more residual power is willing to accept all requests, because it has enough residual battery power, therefore, much traffic will be injected to that node. In this case, the energy decay rate of that particular node will tend to be high and causes a sharp decay of its backup battery power. As a consequence, node exhausts its energy quickly and cause nodes' death rate high in the network. Hence, it causes uneven energy dissipation among the nodes in the network. Moreover, it decreases information transmission efficiency of the network drastically. In this research paper, a Multi-criterion Fuzzy logic based intra-cluster and inter-cluster multi-hop data dissemination protocol is proposed to make balance among the nodes and chooses more stable nodes as CHs for efficient data dissemination. The simulation results have been confirmed that our proposed approach is more efficient than state-of-the-art approaches.
