Multihop Performance of Cooperative Preamble Sampling MAC(CPS-MAC) in Wireless Sensor Networks

Cooperative Communication (CC) is a promising technique to combat fading in a wireless environment. In the authors' previous work, they proposed Cooperative Preamble Sampling (CPS)-Medium Access Control (MAC) protocol which highlighted the benefits of using CC in Wireless Sensor Networks (WSN). Initially, CPS-MAC performance was evaluated in a 3-node network comprising a single source, partner, and destination node. In this paper, they evaluate the performance of CPS-MAC in a multi-hop WSN configuration, where a large number of sensor nodes are deployed around a sink to create a data gathering network.
