“…Let us recall that a collision occurs if two or more nodes choose the same first slot. Consider a contention window CW, the probability that each node chooses a slot is 1/CW [8]. A successful contention period is that one node chooses the first slot, and all other nodes choose later slots.…”

“…To avoid these problems, when there is a collision, all contending sensors reduce its contending probability to a half [8]. Contending probability is the probability that sensors wake-up and go to contention period.…”

“…The probability of collisions is in conjunction with the probability of success [9]. Hence, if there are N transmissions at the same time, the probability of collision (P colln ) [8] is thus calculated as…”

In Wireless Ad hoc network, cooperation of nodes can be achieved by more interactions at higher protocol layers, particularly the MAC (Medium Access Control) and network layers play vital role. MAC facilitates a routing protocol based on position location of nodes at network layer specially known as Beacon-less geographic routing (BLGR) using Contention-based selection process. This paper proposes two levels of cross-layer framework -a MAC network cross-layer design for forwarder selection (or routing) and a MAC-PHY for relay selection. Wireless networks suffers huge number of communication at the same time leads to increase in collision and energy consumption; hence focused on new Contention access method that uses a dynamical change of channel access probability which can reduce the number of contention times and collisions. Simulation result demonstrates the best
