Security is a critical problem when implementing Mobile Ad Hoc Networks (MANETs) and is widely acknowledged. This paper describes the effects of selfish nodes in MANETs. An Ad Hoc Network is a collection of wireless mobile hosts forming a temporary network without the aid of any centralized administration or standard support services. One of the different kinds of misbehavior is node selfishnes...

The TCP protocol exhibits poor performance in multi-hop Mobile Ad Hoc Networks (MANETs). The ultimate reason for this is that MANETs behave in a significantly different way from traditional wired networks (like the Internet) for which the TCP protocol was originally designed. In particular, route failures and route changes due to node mobility may be frequent events in MANETs. Furthermore, cong...

A mobile ad hoc network (MANET) is an interconnected system of mobile hosts without a fixed infrastructure. In MANETs, each mobile host has multi-hop transmission capability, and it has to serve as a router. Because of the dynamic topology and limited resources of mobile hosts, the routing scheme in MANETs presents an important challenge. To improve battery power efficiency in MANETs, many rout...

Mobile Ad-hoc Networks (MANETs) are important in pervasive computing systems, in which users discover and utilize various services to achieve their goals. Integrating service discovery with efficient route discovery protocol in MANETs can greatly improve the efficiency of pervasive computing systems, and hence an efficient route discovery protocol in MANETs is desirable. In this paper, a Locati...

Mobile ad hoc networks (MANETs) are formed by mobile nodes without the support of fixed infrastructure. In the MANET, each node performs as a host as well as host to forward the data packets. The nodes are adjustable based on the local environments. MANETs are used in many situations where temporary network connection is needed. In this paper, investigates the problem of lifetime enhancement of...

Abstract A critical requirement in Mobile Ad Hoc Networks (MANETs) is its ability to automatically discover existing services as well their locations. Several solutions have been proposed various communication domains which could be classified into two categories: (1) directory based, and (2) directory-less. The former efficient but suffers from the amount of control messages being exchanged ma...

Mobile computing is the most powerful application for network communication and connectivity, given recent breakthroughs in field of wireless networks or Ad-hoc (MANETs). There are several obstacles that effective confront must be able to transport data from one system another with adequate precision. For applications, a framework ensure retrieved reflects transmitted data. Before driving other...

In this paper, the author explore the challenges with respect to the security aspect in MANETs and propose a new approach which makes use of a bio-inspired methodology. This paper elaborates various attacks which can be perpetrated on MANETs and current solutions to the aforementioned problems, and then it describes a Bio-Inspired Method which could be a possible solution to security issues in ...
