A mobile ad-hoc network is an autonomous system of mobile nodes connected by wireless links in which nodes cooperate by forwarding packets for each other thereby enabling communication beyond direct wireless transmission range. The nature of ad-hoc networks makes them vulnerable to attacks especially in routing protocols. Providing security in mobile adhoc networks has been a major issue over t...

Ad Hoc networks does not connected central mode. It is infrastructure less wireless network. Due to high mobility of nodes and multipath propogations topology of this network is dynamically changes. It is self configured network. No. of mobile nodes are connected internally in this network. Mobile Ad Hoc networks protocols are different from other internet protocols of infrastructure based wire...

In pervasive computing environment, mobile ad-hoc group gaming will become one of the signficant entertainment applications. Mobile ad-hoc group gaming is where players form their wireless local network and play network games using wireless heterogeneous devices. In network games, it is important to synchronize game states among players appropriatly for keeping entartaining interactivity. Howev...

Ad hoc networks are wireless mobile hosts collections forming a temporary network without any infrastructure/centralized administration. So a mobile host is required to enlist the help of other hosts to forward packets to destination because of each mobile host’s limited range of wireless transmission. The paper presents a protocol for routing in ad hoc networks using Dynamic Source Routing (DS...

A Mobile ad-hoc network (Manet) is a system of wireless mobile nodes dynamically self-organizing in arbitrary and temporary network topologies. People and vehicles can thus be internetworked in areas without a pre-existing communication infrastructure, or when the use of such infrastructure requires wireless extension. Therefore, such networks are designed to operate in widely va ying environme...

Wireless networks with movable base stations combine the advantages of mobile ad hoc networks and wireless LAN to achieve both flexibility and scalability. We present the hierarchical mobile wireless network (HMWN) to support movable base stations. HMWN may be applied to ad hoc networks as well to build a virtual hierarchy. In such a system, mobile hosts are organized into hierarchical groups. ...

A mobile ad-hoc network (MANET) is a self-configuring infrastructure less network of mobile devices connected by wireless. MANETs are restricted to a local area of wireless devices, while others may be connected to the Internet. Cluster techniques used to grouping the mobile nodes to sending data simultaneously to the each group. Each and every group have their cluster header that storing infor...

A Mobile ad hoc network is a collection of wireless mobile nodes connected to form a temporary wireless network without using any communication infrastructure. Due to limited network resources and in order to exchange data packets within the network, wireless multiple hops route scheme adopted for mobile node’s connection. Researchers, with the increasing importance of applications in nonmilita...

Maintenance of the cache consistency is a complicated issue in the wireless mobile environment. Caching of frequently accessed data items on the node can reduce the bandwidth requirement of the mobile node environment. In this paper, we present a new technique called Modified Energy Efficient Cache Invalidation Algorithm (MEECIA) especially to reduce the uplink bandwidth consumption in the wire...

The IEEE 802.11 medium access control (MAC) protocol is a standard for wireless LANs, it is also widely used in almost all test beds and simulations for the research in wireless mobile multi-hop ad hoc networks. However, this protocol was not designed for multi-hop networks. Although it can support some ad hoc network architecture, it is not intended to support the wireless mobile ad hoc networ...
