KAIZEN AND 5S ITS IMPLENTATION IN A SELECTED INDUSTRY

Abstract

Extensive usage of wireless sensor networks is the reason of development of many routing protocols. Routing in sensor networks is a challenging issue due to limited energy, low processing capability and smaller storage area. Efficient usage of energy is a key concern in wireless sensor networks for better performance and longer network life, as sensor nodes work unattended and have limited battery power. In this thesis, different routing algorithms have been discussed but the survey focus was on geographic routing. An energy efficient and routing hole healing, location based protocol HHEAA (Hole Healing Energy Aware Algorithm) has been presented for wireless sensor networks for better performance in data delivery and giving longer life time to the network by balancing the energy consumption of nodes. In HHEAA, each node takes decision for the selection of next hop locally. This algorithm works on location as well as energy level information. Each node knows about its own location and its available energy level as well as the location and energy level of its neighbors. Then forwards packet based on average energy and distance of the neighbors. It also works well in case of formation of routing holes. Simulation was made using OMNET++. Simulation results show that the proposed algorithm is energy efficient and is better than Greedy Algorithm as it shows higher packet delivery rate and lesser number of dead nodes. The proposed algorithm can accommodate thousands of nodes in sensor networks and can give longer life to the network.
