Understanding LEACH Protocol in Wireless Sensor Networks

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 idea behind LEACH is the …

Performance Metrics in Wireless Sensor Networks

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 however varies according to need …

Schemes for Energy Efficient Wireless Networks

OFDMA Networks: The subcarriers and powers can be allocated according to user’s requirement. 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 consideration of circuitry consumption for …
