Abstract: Sensor networks are formed by fixed or mobile sensor nodes and their functions is to capture the events that occur within a certain area and then relay to a central node. Normally sensor nodes are not able to transmit or receive information over long distances due to the need to use less energy and thus extend their useful life. Therefore, the number of sensor nodes in a given area directly influences the coverage of this area and the ability of information to be relayed by several sensors to the central node. Therefore, if there are many missed messages the application will have its performance compromised. In this paper we use a statistical method-based approach to estimate the probability of message loss and area overage from the variables: node displacement velocity and sensor quantity. The results obtained are compared analytically with simple cases in order to validate the results obtained by the simulations performed.
