Analysis of DSDV & AODV for Disaster Management System in Coal Mines

Coal miners encounter many problems in terms of safety during coal production and development of coal industry. During mining operations at deeper and remote areas of the mine, it is hazardous to work without any communication facilities. Miners are constantly exposed to drastic change in environment with fluctuating temperature and pressure. Often it goes unnoticed as accidents do occur in coal mines and hence disaster. Ad-hoc networks are characterized by random and quickly changing topologies which demand for an efficient routing protocol to accommodate the particular environment. In this paper, the mining environment and its constrains are considered to find the suitable and effective protocol. The two most popular and distinct feature protocols: proactive(DSDV) and reactive(AODV) are considered. NS-2 simulator is used to create the mining scenario having access points and miners(mobile nodes). Various characteristics of the network such as packet delivery fraction (PDF), end to end delay using AWK files, varying the speed of mobile nodes and the simulation time. We have achieved the design of a prototype, by considering a base station and mobile node (miner). The prototype senses the changes in environmental conditions and warns the miner of forth coming disaster.
