Interference Management in Wireless Sensor Networks, Part I: Dynamic Semi-distributed Mechanisms

Interference control and management in wireless sensor networks is a challenging task. Fast and dynamic allocation of wireless sensor communications sub-channels would lead to an efficient exploitation of available capacity and traffic variations. It seems a collective decision in a centralized entity is the best way forward for interference management as the centralized decision making entity which is aware of all the sensor nodes, can avoid the conflicting situation where multiple wireless sensor entities within different cells might show interest in the same radio sub-channel and attempt to occupy it leading to a catastrophic increase of interference within that specific radio sub-channel. In current paper dynamic semi-distributed mechanisms for interference management in wireless sensor networks is proposed to take advantage of both centralized and distributed interference management schemes on a localized basis to improve the QoS in wireless sensor networks.
