Optimized Route Selection on the Basis of Discontinuity and Energy Consumption in Delay-Tolerant Networks

摘要

Delay-Tolerant Networks (DTNs) are intermittently connected mobile wireless networks in which the connectivity between nodes changes frequently due to nodes movement. A delay-tolerant network suffers from nodes energy efficiency issues due to frequent mobility and reliable transmission of data packet from source to destination. Due to the mobility of the node there are frequent changes in the path. Due to which enormous amount of energy is wasted. So to conserve the energy of the node energy efficient transmission from one node to another node can be achieved by using the proposed algorithm EADBNHS. Connectivity of the network can be determined by Synchronism, Simultaneousness and Discontinuity using EADBNHS. EADBNHS is the algorithm devised for energy efficiency in this article. To achieve energy efficiency of a node the algorithm is designed in a way, which includes transmission energy, reception energy and the health of the node. This algorithm supports energy efficient transfer of data packet; it selects a node on the basis of minimum energy available on the node and on the basis of its connectivity to other nodes. With the help of Synchronicity, Simultaneousness and Discontinuity we can easily judge a node's condition to become the participant node in the path from source to destination.
