Mobile ad hoc networks (MANETs) play a significant role for communication whenever infrastructure is not available. In MANET, the group communication-based applications use the multicast routing protocol, where there is a single sender node and a group of receiver nodes. The benefits of multicast routing protocols are the capability to reduce the communication costs and saving the network resources...
Mobile ad hoc networks (MANET) is a type of networks that consists of autonomous nodes connecting directly without a top-down network architecture or central controller. Absence of base stations in MANET force the nodes to rely on their adjacent nodes in transmitting messages. The dynamic nature of MANET makes the relationship between nodes untrusted due to mobility of nodes. A malicious node may...
Mobile ad-hoc network is networks that are collection of mobile device that can communicate and share information between each other, without any predefine infrastructure or centralized system. Another challenge in MANET is energy constraints because each of the mobile nodes is operated by limited energy battery. This paper presents a new on-demand power saving routing algorithm for mobile ad-hoc...
A mobile adhoc network is an independent system of mobile stations associated by wireless link to form a system. This system can be modeled in the form of an uninformed graph. Adhoc networks are peer to peer, multihope networks were data packets are transmitted to a source to destination through intermediate nodes (which serve as router). The infrastructure is not the main issue to setup MANET and...
Adhoc wireless networks are defined as the category of wireless networks that utilize multihop radio relaying and are capable of operating without the support of any fixed infrastructure and hence they are also called infrastructureless networks. This type of network allows for spontaneous communication without previous planning between mobile devices. A variety of routing protocols for adhoc wireless...
This paper is concerned with a crucial problem of MANET which is congestion control (CongClt). CongClt can be described as a mechanism used to control congestion (Cong) and keep the traffic below the capacity of the network. Many approaches have been proposed to overcome CongClt in Ethernet as well as in MANET. Controlling the Cong in MANET is quite difficult due to its fundamental characteristics...
DSR protocol is less considered for practical application due to its more limitations against other routing protocols. Modification in DSR protocol can make it considerable and it can improve energy efficiency to enhance lifetime of battery operated mobile adhoc networks. This paper proposes the modification for route discovery mechanism in normal DSR protocol for energy efficient route establishment...
Mobile ad-hoc network (MANET) is an autonomous system of mobile nodes connected by wireless links; each node operates as an end system and a router for all other nodes in the network. Nodes in mobile ad-hoc network are free to move and organize themselves in an arbitrary fashion. The path between each pair of the users may have multiple links and the radio between them can be heterogeneous. Use of...
On the case of most important systematic issue that must need to be solved in means of implementing a data transmission algorithm on the source of Mobile adhoc networks (MANETs). That is, how to save mobile nodes energy on meeting the requirements of applications or users as the mobile nodes are with battery limited. On while satisfying the energy saving requirement, hence it is also necessary of...
In this paper, we propose a new routing protocol for ad hoc wireless networks, which is based on DSR (Dynamic Source Routing) on-demand routing protocol. Congestion is main reason for packet loss in mobile ad hoc networks. If the workload is distributed among the nodes in the system based on the delay of the paths, the average execution time can be minimized and the lifetime of the nodes can be maximized...
In ad hoc mobile networks (MANET), the mobility of the modes is a complicated factor that significantly affects the effectiveness and performance of ad hoc routing protocols. Mobility and traffic patterns for each node such as intermediate and end nodes are restrained to extract features of each routing protocol. In this paper, we focus on the performance of the routing protocols for stationary end...
