THP: Triple Heterogeneous Protocol for Energy Efficient WSNs

Computer Engineering

Wireless sensors network is a network to collect data with the help of randomly deployed sensors nodes. This data is collected at the centralized resource rich node also known as base station. So every sensor in the network senses the phenomena and converts this phenomenon in the form of data. Now this data is transferred by the sensor nodes to the base station. The role of base station is to collect data sent by individual sensor in the network. Every sensor node in the network is resource constrained in terms of energy, processing power and memory. Whenever an operation is performed by sensor node, a small amount of energy is consumed which depends upon the type of operation. LEACH (Low-Energy Adaptive Clustering Hierarchy), is a clustered based energy efficient protocol that utilizes randomized rotation of local cluster head to evenly distribute the energy load among the sensors in the network. LEACH uses data fusion into the routing protocol to reduce the amount of information that must be transmitted to the base station which saves energy in the network. LEACH is a homogenous routing protocol in which only one type of sensor nodes are there in the network. Every node has same amount of resource as compared to any other node in the network. Stable Election Protocol (SEP) is a modification in LEACH protocol which is heterogeneous wireless sensor network. In SEP protocol, two types of sensor nodes are there in the network, one with limited amount of energy and second more powerful nodes with more energy. SEP protocol is more energy efficient as compared to LEACH protocol. In this research work, we design Triple Heterogeneous Protocol (THP) network. In THP network, the heterogeneity of Stable Election Protocol (SEP) is extended from 2-Level heterogeneity into 3-Llevels heterogeneity. In THP network, there are three types of sensor nodes, i.e. normal, intermediate and advanced sensor nodes. This leads to a network refers to as a 3-Tiers WSNs architecture. Simulation result proves that THP network protocol is better in terms of energy as compared to LEACH and SEP protocol
