Abstract: A Wireless ad hoc network is a collection of autonomous mobile nodes that communicate with each other over wireless links without any fixed infrastructure. The nodes use the service of other nodes in the networkto transmit packets to destinations that are out of their range. A number of ad-hoc routing protocols have been proposed and implemented which include ad-hoc on demand Vector Protocol (AODV) , dynamic source routing (DSR) and Destination sequenced Distance Vector (DSDV) routing protocols. In this paper for experimental evaluation purposes, we have considered 600m x 600m, terrain area which illustrates the performance in terms of the packet delivery fraction, average end-to-end delay ,normalized routing load and throughput for routing protocols. Our simulation results using NS-2 shows that DSDV performs best in all the cases of packet delivery fraction, average end-to-end delay , normalized routing load and throughput over other routing protocols on varying mobility speed using G

Abstract: This paper presents the checking and monitoring of weather parameters in agriculture zone by the system of automation of weather station in agriculture zone using Zigbee. In the system architecture the wireless sensors network devices are used to check and monitor different weather parameters in agriculture zone to avoid or to solve the difficulty of checking and monitoring different weather parameters in agriculture zone using wires and different analog devices during some weather or environmental hazards. The monitoring different weather parameters are always plays very important role in the process of the farming production. To send the weather related information or guidelines using GSM SMS technique to the farmers to plan their farm in a better way, the Zigbee/IEEE802.15.4 based wireless sensor network is utilized in the system architecture. The weather parameters like humidity in the soil, temperature, and wind speed and wind direction in the agriculture zone are measured by the
