چکیده:
One of the fundamental design challenges in designing a Wireless Sensor Network (WSN) is to maximize the network lifetime, as each sensor node of the network is equipped with a limited power battery. To overcome this challenge, different methods were developed in the last few years using such techniques as network protocols, data fusion algorithms using low power, energy efficient routing, and locating optimal sink position. This paper focuses on measuring robustness of a net work and we show how selecting sink nodes in network is important to achieving high robustness level of the network. First we argue how positions of sink nodes, affect networks robustness and how our proposed method works to solve this problem. We present sets of metrics to measuring the suitability of nodes to be selected as sink node. With having suitability degree for each node the risky nodes have low chance to be selected. And also after ranking the nodes we present a simple method for selecting suitable nodes as sink nodes. Our simulation results show that the presented method leads to better results and high robust network and performance of network improved remarkably
