The Mobile Ad hoc and Sensor Network Systems group conducts R&D for mobile ad hoc and sensor network systems and technologies for civilian, industrial and military applications. The overall objective of the group is to optimize layout, configuration, functionality and performance of such systems. Objectives include convergence of mobile wireless networks and the Internet; inter-layer protocol interaction, service discovery and location; and improved routing, security, QoS and power consumption mechanisms within wireless ad hoc/sensor networks. The resulting R&D is used to support the Communication Research Center's Major Program initiatives, Industry Canada, National Defence, and Canadian industrial development in the execution of their mandates and R&D programs as well as to support international R&D collaboration undertakings.
