In Wireless Sensor Networks (WSNs), it is imperative to utilize the most power efficient techniques to prolong the lifetime of a sensor node. Minimization of power consumption in WSN's has been discussed extensively in literatures. Usually, central nodes (e.g. cluster head nodes) in WSNs consume large amount of power due to the necessity to decode every received packet regardless of the fact that the transmission may suffer from packets collision. Unlike other power consumption techniques, instead of decoding every received signal at the central nodes which consume too much power, they propose a suite of novel, yet simple and power-efficient technique to detect a collision without the need for full-decoding of the received packet.
