Node Filtering and Face Routing for Sensor Network

Greedy forward routing and face routing algorithms have been extensively used for sending messages in sensor networks. In this paper, we consider the problem of filtering redundant nodes in a sensor network as a pre-processing step for face routing. We propose an algorithm for identifying redundant nodes. We test the performance of proposed filtering algorithm on generated networks. The prototype algorithm for testing the proposed algorithms has been implemented in the Java programming language. Experimental investigation shows that the proposed filtering algorithms are effective in removing redundant nodes without compromising the network connectivity.
