Emerging applications in the area of wireless sensor networks that include a wide variety of scenarios typically involve a significant number of nodes deployed in a wide area. To ensure proper communication between the network nodes to the base station, the messages are propagated by intermediate nodes, so a route with multiple links is established. In general, sensor nodes are characterized by limited resources; therefore it is essential to use protocols that ensure not only communication but also that save the most energy while providing scalability. Different routing protocols have been proposed for WSNs, but the reactive routing algorithms have shown be more energy efficient, which makes them suitable for wireless sensor networks. In this paper the performance of the reactive type protocol (Ad -Hoc On Demand Distance Vector) is evaluated under the simulation platform OMNeT++ through different scenarios . The AODV protocol has been chosen by the performance superiority comparing with other reactive protocols reported in the literature. The protocol has been evaluated under the following metrics: packet delivery rate, average end-to-end delay, routing overhead and energy consumption. The results show that AODV reduces their performance when the number of nodes increases, consequently it restricts the network scalability, further results show that the spatial distribution of the nodes affect on the performance of the protocol, specific in our work, the uniform distribution shows better results.
