Despite the disparity in the objectives of sensor applications, the main task of sensor networks is to sense and collect data from a target domain, process the collected data, and transmit the information back to the base station. Achieving this task efficiently requires the development of an energy-efficient routing protocol to set up paths between sensor(More)
One of the fundamental services provided by a wireless sensor network (WSN) is the monitoring of a specified region of interest (RoI). Considering the fact that emergence of holes in the RoI is unavoidable due to the inner nature of WSNs, random deployment, environmental factors, and external attacks, assuring that the RoI is completely and continuously(More)
The Network Simulator (NS-2) is a most widely used network simulator. It has the capabilities to simulate a range of networks including wired and wireless networks. In this tutorial, we present the implementation of Ad Hoc On-Demand Distance Vector (AODV) Protocol in NS-2. This tutorial is targeted to the novice user who wants to understand the(More)
Sensor network lifetime strongly depends on the used routing protocol. Using several definitions of lifetime and a common evaluation framework, we have analyzed the lifetime of some representative flat and hierarchical sensor network routing protocols, namely: DIRECT, FLOODING, GOSSIPING, LEACH and HEED. Extensive simulations have been carried out yielding(More)
Sensor placement is a fundamental issue in wireless sensor networks (WSNs). The sensorpositions can be predetermined to guarantee the quality of surveillance provided by the WSN. However, in remote or hostile sensor field, randomised sensor placement often becomes the only option. In this paper, we survey existing random node placement strategies. We(More)
