LEACH, Low-Energy Adaptive Clustering Hierarchy, is an application-specific protocol architecture for Wireless Sensor Network (WSN). It has become one of the bases for developing new architecture protocols or modifying the existing one in WSN. It is an adaptive and self-organizing protocol that minimizes the energy consumption in WSN. The underlying

Read more →OMNeT++ is a discrete event based network simulation framework which provides modularity in open architecture for simulation of computer and related communication networks. OMNeT++ Modeling and Simulation is being used by many researchers and academicians in recent years. We present here basic step by step guide to use OMNeT++, its
Read more →The application and importance of sensor network depends on the type of sensor nodes used, the field & scope of deployment, the computational and QoS requirements. Event detection, location sensing, control of actions to be taken under certain criteria are frequent requirements in sensor networks. Sensors vary from seismic, low
Read more →Sensor network differ from the traditional ISO OSI Model of Communication Standards. Sensor nodes are not necessarily IP equipped and the seven layers of OSI model are in harmony with just three protocol stacks, namely, power management plane, mobility management plane and task management plane. This protocol stack performs functions
Read more →The design of SN is a challenge because many influencing factors such as fault tolerance, scalability, production cost, operating environment, network topology, hardware constraints, transmission media, power consumption and others have to be considered. The performance of the network is then measured based on quantifiable parameters called performance metrics. This
Read more →SN can form the base of cloud computing, distributed computing, and Next Generation Networks (NGN). For this, sink nodes can be used as a gateway to interconnect other networks, and backbone scenarios for more connected networks. Router equipped with sensing capabilities can work for saving powers and sleep when there

BS dynamically controls the resource allocation in two categories – Rate Adaptation (RA) which maximized thru put and Margin Adaptation (MA) which minimizes the total transmitted power. The frequency diversity is yet to be exploited with the
