An Enhanced I-spin to improve the Energy Efficiency for Wireless Sensor Networks

Abstract
A wireless sensor network (WSN) is made up of spatially distributed autonomous sensors to monitor various conditions such as physical or environmental conditions. And cooperatively pass their data through the network to a main location. The challenge remains in designing a good routing protocol which provides the solution for various issues such as energy awareness, adaptability and computational speed. But in WSN the main area of concentration is that of using a minimal energy resources and routing a data in an efficient manner. But in a network, energy loss is due to the routing of data. Protocols like classical flooding, ideal case, gossiping, spin and i-spin can reduce the consumption drastically due to the redundancy and resource blindness. To overcome this disadvantage, we present a novel protocol called enhanced i-spin which has a meta data descriptor and the data is sent on the shortest path. On performing simulation of enhanced i-spin, we compared the above mentioned protocols, and the graph results prove that i-spin has higher percentage in disseminating data at a fixed energy level.

I.Introduction
A wireless sensor network (WSN) consists of spatially distributed autonomous sensor to monitor physical or environmental conditions such as temperature, sound, vibration, pressure, motion or pollutants and to cooperatively pass their data through the networks to the main location. It contains large number of sensor nodes in which it either phenomena or very close to it. The protocols used in a WSN to be self-organizing and should be the energy of sensor networks. It is used to processed data instead of sending the raw data to the nodes.
SENSOR NETWORK CHALLENGES AND KEY ISSUES
It contains the enormous application of WSN’s and it to be constrained in a bandwidth and energy supply. It poses the unique constraints and hardware I it. A. Some of the Major Challenges Nature of deployment, self-configuration, Reliability, quality of service, mobility, security. B. System Architecture and Design Issues of Sensor Networks It is used to build of “nodes”-from a several thousands of nodes is connected to one sensors. Each network is typically several parts. A sensor node consists of radio transceiver, and it contains both transmitter and receiver in a single unit. Simply we can imagine that the sensor nodes can be done in small computers, and it is basic in terms of interfaces and components and it usually contains computational power and limited memory, sensors or MEMS.
