A Survey on Cluster Schemes in Ad Hoc Wireless Networks

摘要

Efficient Cluster schemes play an important role in the self-organizing Ad Hoc wireless networks. This paper surveys and compares recent cluster schemes. We classify some of these schemes into the 3 major categories of (1) energy efficient schemes, (2) K-tree schemes, and (3) management schemes. Issues in these schemes are considered: overlaps between the clusters; Clusterhead (CH) not at the center of the cluster; higher power consumption in CHs than in normal nodes; energy wasted by duplicated transmission of data. A TMDA dynamic cluster (TDC) algorithm trying to solve these problems is also proposed for Ad Hoc wireless sensor networks.
