  • Conference Proceeding: TC-PAR: Topology control for multi-hop wireless sensor networks using preferential attachment rule

    ABSTRACT: We present a topology control algorithm for multi-hop wireless sensor networks with preferential attachment rule. Each node controls its transmission power, and decides its nearest neighbouring node set in order to preferentially link from a new node. Our objective is to use preferential attachment rule to establish a topology based on the scale-free model which has good overall performance in terms of fault tolerance and time efficiency.

    ABSTRACT: Topology control for fault tolerant communication is one of the important issues in wireless sensor networks. This paper presents a simple mechanism of fault tolerant topology control for generating undirected scale-free networks, where the network evolution is determined by the rules of growth and preferential attachment. The authors prove that this mechanism produces scale-free networks with degree exponent gamma = 1. The dynamic analysis found that this evolution model can maintain the character of scale-free networks and can improve the uniformity of the degree distribution of the networks as compared with Barabasi and Albert model.
