MANET networks (Mobile Ad hoc Networks) are a sub class of mobile and wireless networks. In this type of network, all the nodes are mobile and no fixed infrastructures are considered existing. Among the challenges of the MANET, the stability and the durability of the selected paths in the network. In a previous work, we proposed a solution to this challenge by taking into account the mobility of nodes...
In military operation, sharing information among troops is essential issue for effective combats and minimal causalities. So these tendencies take militaries to information centric combat. And MANET has proper properties for this military operation such as infrastructure less, effective data transfer and flexible for changeable topology. Routing protocol is key factor of MANET. So to apply MANET into...
In the field of telecommunications, mobility represents new practical ways of communication that are known to be vaguely flexible in terms of use; for users expect to enjoy constant and good quality service. An attempt will be make; all along this file; to introduce the concept of Multihoming to mobile networks in order to increase their strength and resistance toward the effects of mobility, along...
This paper analyzes the problems in the wireless network caused by using minimum hop count as its routing metric, and discusses ETX metric which invented by De Couto to solve these problems and the shortage of it in mobile environment, then modifies it by relatively counting as to make it suitable for such environment. This paper uses the new ETX as a metric for the OLSR routing protocol, and proves...
Wireless internet has become popular in recent years due to the tremendous growth in the number of mobile computing devices and high demand for continuous network connectivity regardless of physical locations. In this paper, we investigate the effects of routing protocols on the performance of Transmission Control Protocol (TCP) variants in multi-hop wireless networks. Through simulations we study...
This paper describes the architecture of a self-configuring multi-hop mobile network and analyse the performance of the ad-hoc routing protocols. A testbed is deployed to analyse the performance of the ad-hoc routing protocols in a self-configuring multi-hop environment. The testbed comprises of a set of mobile nodes and an Internet gateway. The mobility of the nodes and the resulting network topology...
The challenges of optimal flooding of network control messages in mobile ad-hoc network (MANET) have been well studied in the literature [2]-[10] and [12]-[19]. A particular case of this problem is encountered in MANET routing protocols, which need to distribute routing control information to all member nodes as efficiently as possible. While both proactive and reactive MANET routing protocols exist,...
Ad hoc networks are a new wireless networking paradigm for mobile hosts. Unlike traditional mobile wireless networks, ad hoc networks do not rely on any fixed infrastructure. Instead, hosts rely on each other to keep the network connected. The military tactical and other security-sensitive operations are still the main applications of ad hoc networks, although there is a trend to adopt ad hoc networks...
Multi-hop wireless ad hoc networks have the potential to dramatically reduce the cost of deploying communication infrastructure. However, the nature of this technology limits the capacity of radio links. Thus, it is important to utilize them as efficiently as possible. Routing in ad hoc sensor networks is a complicated task because of many reasons. For traffic engineering, multipath capabilities are...
