This paper studies the MAC layer performance in demanding wireless sensor networks. The requirements for wireless MAC are discussed based on a prominent CSMA-based MAC protocol evaluation varying critical network parameters. The objective is to investigate the current radio access technologies suitability for wireless sensor networked applications. The channel access mechanisms are analyzed in more...
As tracking applications for moving objects become more challenging, demands for accurate and reliable tracking methods using wireless sensor networked devices increase. The use of received signal strength (RSS) of the propagated signals, provided by most sensor radios, is the popular means of achieving such a task. Despite the great RSS variation, which may result in inaccurate estimation of the...
