ABSTRACT  Wireless sensing network uses very light sensors which have very low power backup owing to this power saving is very significant role in such type of network. Suggested algorithm “Odd - Even virtual scanning” is used to detect any object efficiently, effectively and it also saves significant power in wireless sensors. It periodically switches the sensors between sleeping and awake mode where the detection of targets, entering from the entrance point, before they approach one of the end point of protection area. Earlier some work like virtual scanning algorithm used sensors wake up one by one for w seconds along road segments, creating waves of sensing activities called virtual scanning. That’s works were significant in terms of search and rescue operations, where a scanner or observer visually searches the search space for distress signal where as odd- Even virtual scanning is an improved method for scan the object. It detects the energy of an object inside scanning area as well as it also saves energy consumption by this work opens a promising detection of road network surveillance. It focuses reduction energy consumption and it improves the life time of sensor. The detection is guaranteed but energy utilization is maximize in network life time The performance of the odd- Even scanning approach in terms of network time is better than all other previous scanning algorithms in terms of network time. All the previous techniques focus on energy consumption but here paper focus on reducing the detection time as well as energy consumption. This scan based method can achieve significantly better performance then duty cycling algorithm.
