Description

Wireless Sensor Networks (WSNs) have emerged as research areas with an overwhelming effect on practical application developments. The aim of the project is to improve the link stability in distributed wireless network. We proposes a model for the energy consumption of a node as a function of its throughput in a wireless CSMA network. We first model a single-hop network, and then a multi-hop network. We show that operating the CSMA network at a high throughput is energy inefficient since unsuccessful carrier sensing attempts increase the energy consumption per transmitted bit. Operating the network at a low throughput also causes energy inefficiency because of increased sleeping duration. Achieving a balance between these two opposite operating regimes, we derive the energy-optimum carrier-sensing rate and the energy-optimum throughput which maximize the number of transmitted bits for a given energy budget. For the single-hop case, we show that the energy-optimum total throughput increases as the number of nodes sharing the channel increases. For the multi-hop case, energy-optimum throughput decreases as the degree of the conflict graph corresponding to the network increases. We proposed the system for high performance of the wireless network through the link stability (OLSR) concept use of the routing algorithm. The issues in this system are scalability to large number of nodes, design of data handling techniques, localization techniques, real time communication, data availability, fault tolerance etc. By using the proposed model, the system overcomes the current issues and system complexities.
