Reducing the Packets Loss Using New MAC Protocol

Abstract

Data move from one point to another point is very important for any network. A Network is mainly used the Mac protocol for communication. The Mac layer could be a sublayer of the data link layer. It is accountable for providing dependableness to the higher layers for purpose to point connections established by the physical layer. Technically, the Mac sublayer is the bottom part of the data link layer of the OSI model. The M ac protocols to confirm that signals sent from completely different stations across a similar channel do not collide. In this work I have implemented a novel cross layer protocol - SNAPdMAC.The protocol adjusts the upper and lower bounds of the contention window to lower the number of collisions. It also uses a power control scheme, triggered by the MAC layer to limit the packet loss, energy wastage and to decrease the number of collisions. The protocol has been implemented an d then compared with two other Mac protocols in ns2 namely: 802.11 MAC Protocol Standard and Sensor MAC (S - Mac) protocol. I will compare the protocols based on the total number of packets received and also compared them based on the network lifetime. The results show that SNAPd MAC per forms fairly better than the standard 802.11 protocols.
