Competition: Using Enhanced OF∂COIN to Monitor Multiple Concurrent Events under Adverse Conditions

Monitoring various states of multiple nodes reliably and timely in narrow-band and power-constrained wireless sensor network is extremely challenging, not to mention in existence of interference. An enhanced Oriented Flooding protocol with Partial COnstructive INterference (eOFPCOIN) is proposed to collect the states of sources via many-to-many communication. Basically, eOFPCOIN is based on two phenomena, i.e., constructive interference and the capture effect. To boost the dependability against interference, eOFPCOIN further exploits a channel-hopping scheme. Furthermore, eOFPCOIN maintains a light-weight topology model to achieve oriented many-to-many communication.
