Coloring-Based Channel Allocation for Multiple Coexisting Wireless Body Area Networks: A Game-Theoretic Approach

ABSTRACT:

This paper addresses the problem of coexistence that arises when multiple wireless body area networks (WBANs) are in use. Co-channel interference can occur between different WBANs if the channels are not allocated properly, which can lead to a reduction in performance in terms of both energy efficiency and the reliability of packet transmission. We model the problem of channel allocation as a coloring problem on a graph and come up with a solution that will increase the amount of co-channel reuse as well as the number of WBANs that have channels assigned to them. A distributed two-hop incomplete coloring (DTIC) algorithm that takes a game-theoretic approach is what we propose as a solution to the issue of graph coloring. The DTIC algorithm uses two-hop information to enable high channel reuse among two-hop neighbors and allows for incomplete coloring when the number of colors (or channels) is insufficient to color all vertices without conflict. This is accomplished by exploiting two-hop information. In addition, a protocol for the distributed passing of messages is proposed in order to achieve collision-free message exchange, as well as to guarantee that WBANs will share coloring information in a consistent manner. The results of our simulations indicate that our proposed algorithm is capable of achieving superior co-channel reuse as well as higher throughput than other methods currently in use.
