Designing of SLEEP and AWAKE Scheduling Algorithm for Packet Delivery in MANETs

In this increasing wireless networks, mobile ad hoc networks (MANETs) are becoming an important aspect in many applications. It is a flexible and self-autonomous wireless network architecture, is very promising to find many important applications in the daily information exchange, disaster relief, military troop communication, etc. In the packet delivery scheme it combines erasure coding and packet replication techniques in MANETs. Packet delivery is enhanced in this scheme. Under this scheme a group of packets is first encoded into coded packets using erasure coding, and each coded packet is then replicated and forwarded to the destination node. The original packets can be recovered when coded packets reach the destination node. Each packet is sent to only one relay node, due to the increase of packets, higher complexity will occur. During the process of packet transmission the nodes are awake all the time and more energy is consumed for the execution time. We propose a new technique called sleep and awake scheduling where the nodes are awake only at the communication time. Sleep and awake scheduling wake up nodes only on packet transmission and reception time.
