Wireless sensor networks are becoming an ideal approach for implementing many
applications because they avoid complex wirings and their maintenance. However.
like other networks, primary source of data communication  are protocols. The MAC
(Medium Access Control) protocol determines when a wireless sensor transmits its
sensor data. However, MAC protocols suffer from collisions and therefore it affects
the eminency of wireless sensor networks. Therefore, efforts must be taken at MAC
layer for improving the overall efficiency of the network.
Ahis thesis provides a model of the LMAC (Lightweight- MAC) protocol for
analyzing the probability of collisions for sensor nodes. Collisions occur hen nodes
transmit data at same time using the same channels. In this work, we consider
connected topologies consisting of five nodes. Ihe analysis is performed using the
model checker UPPAAL. The results show that if the weighting rate of nodes (before
transmitting data), is increased then the number of collisions also decreases.
Furthermore, we also compare the results of five nodes with its 5.6. and 7 times slots
based on the probability of collisions and propose an optimistic choice ofa network
set-up that increases network performance and reduces network cost.
