The goal of

this paper is to describe processes how to simulate the lifetime

of the WSN network during a data gathering. We describe tasks

such as topology generation and visualization, data routing and

communication cost calculation. To estimate lifetime of network,

we have proposed the Matlab energy model that goes the

analysis of the real Zigbe network.-The goal of
