The major issues occurring in these new types of systems are: (a) the continuity of environment monitoring, (b) the mobility management of sensors, (c) the ad-hoc communication scheme, and (d) the security of sensitive messages. This paper develops an ad-hoc architecture and communication and mobility schemes to provide an efficient monitoring system in an environment where targets have unpredicted motion. It also discusses a security solution. A numerical simulation is provided for the validation of our schemes.
