Wireless network is getting popular day-by-day from past few decades due to increasing use of mobile communication and web applications. Due to fast changing features in technology wireless network has also change frequently. Mobile nodes are occasionally confronted with reachability issue. In transmitting packets, generally void problem occurring is not fixed in advance. Thus resolving a void routing problem becomes a big issue. This paper is on void problem which occurs in WSN, so greedy routing algorithm protocol is introduced in their paper that will give guarantee to deliver data packets and also guarantee of resolving control overhead.
