Multi-Metric Route Cost Based Routing in Wireless Multimedia AD-HOC Networks

Abstract

To improve the quality of life, bigger cities in the world addressing their problems by adopting latest technology. IOT connect physical world to the internet and such concept is adopted by bigger cities having large population growth rate. Wireless multimedia sensor network helps to monitor various parts of a city without use of cables. This network becomes the primary component of every smart city due to its surveillance and monitoring capability In contrast with conventional sensor networks, multimedia sensor nodes are equipped with cameras which acquire, process, compress and transmit information about an event happing at some remote area in the form of an image or video. However, like conventional WSNs this network is having multiple constrained and new metric needs to be considered to improve network life time and Quality of service parameters. Multiple metric based route cost function is defined and routing mechanism based upon this cost function is proposed. Since each multimedia sensor node is battery operated and connected through low power wireless links. This work helps to find an optimal path having minimum energy consumption, maximum link reliability, minimum number of hops and minimum routing table magnitude. A cost function considers constraints of wireless multimedia sensor networks. It satisfies desirable network requirements and improves network life time through efficient routing. The proposed algorithm is tested, simulated and compared with previous routing algorithms.
