How Do Wireless Chains Behave? the Impact of MAC Interactions

Free registration required

Executive Summary

In a Multi-hop Wireless Networks (MHWN), packets are routed between source and destination using a chain of intermediate nodes; chains are a fundamental communication structure in MHWNs whose behavior must be understood to enable building effective protocols. The behavior of chains is determined by a number of complex and interdependent processes that arise as the sources of different chain hops compete to transmit their packets on the shared medium. In this paper, the authors show that MAC level interactions play the primary role in determining the behavior of chains.
