An aproach combining leach-pegasis protocols for wireless sensor networks: (Clp-Protocol)

In wireless sensor networks (WSN), minimizing the energy consumed by the sensor node when transmitting or receiving data between nodes or change information with the base station (BS) is very important to maximizes the lifetime of networks for long-term monitoring time, for that energy consumption is the major constraint that influences the architecture of the sensor network, in general the sensor network is limited in energy. In most cases, change the battery of sensor is not possible, this means that the lifetime of a sensor depends greatly on the lifetime of the battery. To solve this problem, it is necessary to choose routing protocols that consume less energy, namely hierarchical routing protocols. The aim of this paper is in first to evaluate the performance of two hierarchical routing protocols in terms of energy consumption by each node in sensor network, namely Protocols Low-Energy Adaptive Clustering Hierarchy (LEACH) and protocol Power-Efficient Gathering in Sensor Information System (PEGASIS), secondly this paper proposes our method routing protocol proposed for the (WSN) based on LEACH and PEGASIS, our proposed method is a combination of LEACH and PEGAIS protols (CLP-protocol).
