In this paper, a protocol called Enhanced Associativity-Based Routing (EABR) - an on-demand protocol - is proposed that can be used in routing for MANETs to provide more stable routing for longer duration than any other existing routing protocols.
Abstract
Mobile nodes are self-organizing and adaptive, changes link in unpredictable manner. When a network is formed by such nodes, it can be termed as MANETs which can be abbreviated as Mobile AD-Hoc Networks. The main characteristic of such networks is lack of any fixed infrastructure like base station, physical medium etc. Different protocols have been proposed to perform routing for such nodes. Continuous data transmission is challenging due to a frequent breakage in route links. Security is also an important aspect which has to be considered in order to route the data through these vulnerable nodes. In this paper, a protocol called Enhanced Associativity-Based Routing (EABR) - an on-demand protocol - is proposed that can be used in routing for MANETs to provide more stable routing for longer duration than any other existing routing protocols. Overhearing and threshold is introduced in the EABR protocol to fight against malicious nodes. Here, EABR is implemented in Spartan-3 XC3S400-5fg320 FPGA Chip. Using NS2 simulator comparison of EABR and ABR protocol is performed. Thus by Using the EABR protocol, network throughput can be increased to 50 percent in the presence of malicious nodes without increasing network bandwidth. (Published Abstract)
