GA-LORD: Genetic algorithm and LTPCL-oriented routing protocol in delay tolerant network

Abstract

In communication systems, there are a number of challenges that make the reliable delivery of data difficult to achieve. In the traditional wireless system, if there was any problem such as disconnection between the intermediate nodes or nodes getting drained off because of low energy, then there was high probability of data getting lost. To solve these problems in delay tolerant network (DTN), we propose two new protocols, viz. the Licklider transmission protocol convergence layer (LTPCL) and a protocol formulated by combination of metaheuristic approaches, viz. genetic algorithm and ant colony optimization: GAACO to select the shortest path for transmission of the packets from source to destination by consuming less energy, less delay, less number of hops, but at the same time delivering high throughput.
