摘要: The broadcast capacity of a wireless sensor network (WSN) is defined as the maximum rate at which may generate messages intended for distribution to entire network. Broadcast limited by factors such communication collisions and excessive queue lengths incurred under heavy loads. Collisions be avoided through use coordination (CC), information (IC), ensuring that only useful are transmitted stored. Our model takes into consideration channel variations (using Rayleigh fading) interference due overlapping transmissions. Any node's transmission can potentially reach every other node in network, provided received signal plus noise ratio (SINR) receiver above certain threshold. results show benefits IC CC well tradeoffs terms cost when using these mechanisms.
