Network Lifetime Evaluation for Grid ML-MAC Protocol
The major problem for wireless sensor networks (WSN) is the limited energy supply so that we can save energy
for future purpose. Most common techniques for prolonging the life time of the network is Routing algorithms etc. In
this paper a multi-layer MAC (ML-MAC) concept is suggested for energy efficient Grid ML-MAC Wireless Sensor Network
(WSN). In Grid Topology sensors are placed manually in an array configuration. Another topology we can place it
in is hexagonal lattice. The efficiency of the proposed multi-layer MAC is validated using QualNet 6.1. Additionally we
also analyze the performance of various parameters like Residual Battery Capacity (mAhr), Average End-to-End Delay
(sec.), Throughput (bits/sec.), and Jitter (s) is evaluated over IEEE 802.15.4 AODV (Ad-hoc on demand distance Vector
Routing Protocol) by applying Grid Topology using ML-MAC concept. The simulation results demonstrate that our solution
significantly improves the overall network lifetime.
