A Mobile Ad-hoc Network (MANET) is a collection of multi-hop wireless mobile nodes among which the communication is carried out without any centralized control or fixed infrastructure. MANET is a self-organized, self-configurable network having no infrastructure, and in which the mobile nodes move arbitrarily. The wireless link in the network are highly error prone and can go down frequently du...

Vehicular Mobile Communication has emerged as a new area of attraction in the field of Wireless communication. VANETs have emerged as a boon towards saving human live by its safety and non-safety potential applications. This paper tests routing protocols namely Ad hoc On Demand Distance Vector (AODV), Ad hoc On Demand Multipath Distance Vector (AOMDV), Dynamic Source Routing (DSR) and Destinati...

Security in MANETs is of prime importance in several scenarios of deployment such as battlefield, event coverage, etc. The traditional non-secure routing protocols for MANETs fail to prevent against attacks such as DoS, spoofing and cache poisoning. One of the primary goals of designing secure routing protocols is to prevent the compromised nodes in the network from disrupting the route discove...

The performances of the routing protocols are important since they compute the primary path between source and destination. In addition, routing protocols need to detect failure within a short period of time when nodes move to start updating the routing table in order to find a new primary path to the destination. Meantime, loss of packets and end-toend delays will increase thereby reducing thr...

Ad-hoc networks are characterized by a lack of infrastructure, and by a random and quickly changing network topology; thus the need for a robust dynamic routing protocol that can accommodate such an environment. Consequently, many routing algorithms have come in to existence to satisfy the needs of communications in such networks. This article presents a simulation study and comparison the perf...

A mobile Ad-Hoc network is a collection of wireless nodes that can dynamically be set up anywhere and anytime without using any pre-existing network infrastructure. It is an autonomous system in which mobile hosts connected by wireless links are free to move randomly and often act as routers at the same time. Mobile ad-hoc network have the attributes such as wireless connection, continuously ch...

In this study, Taguchi method was used to identify the several factors that may affect the performance of Destination Sequence Distance Vector (DSDV) routing protocol. The performance of DSDV routing protocol in mobile ad hoc networks were greatly influence by factors such as node speed, node pause time and traffic load. Problem statement: By using orthogonal experimental design and analysis te...

Worldwide Interoperability for Microwave Access ( WiMAX) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. Demand for such type of mobile broadband services and applications are growing rapidly as it provides freedom to the subscribers to be online wherever they are at a competitive price and other significan...

Wireless networking has become an important area of research in academic and industry. Worldwide Interoperability for Microwave Access (WiMAX) is a technology that bridges the gap between fixed and mobile access and offer the same subscriber experience for fixed and mobile user. Major issues arising in WiMAX network is the selection of the optimal path between any two nodes and route stability....

Due to unpredictable network topology changes, routing in Mobile Ad Hoc Networks (MANET) is an important and challenging research area. The routing protocol should detect and maintain a good route(s) between source and destination nodes in these dynamic networks. Many routing protocols have been proposed for mobile ad hoc networks, and none can be considered as the best under all conditions. Th...
