    All mobile nodes participating in a group communicate with one another in the group through a shared radio link without cable or backbone composes an infrastructureless network, called Mobile Ad hoc Network (MANET). Because network topology may be changed at any time as result of mobility of nodes and the failure of available routes, Quality-ofService (QoS) of real-time multimedia application may have difficulty in satisfying their services. In this paper, we propose a routing scheme for multimedia services called Modified Dynamic Source Routing (MDSR) protocol. The MDSR selects the shortest path by using power level. Our proposed scheme provides lower average delay and mean number of hop path from source to destination than DSR protocol can provide. © 2006 IEEE.

    All communications in a network made by mobile hosts through a shared radio link without cable or backbone, commonly called Mobile Ad hoc Network (MANET). Since the network topology may change constantly because of mobility of nodes and the available routes may fail many times, Quality-of-Service (QoS) of real-time multimedia application may have difficulty in satisfying their services. In this paper, we propose a Routing Scheme for Multimedia Services, which selects the shortest path by using power level Our proposed scheme provides not only the lower means number of hops path from source node to destination node, but also higher thoughput than the conventional scheme. © 2005 IEEE.

    In this paper, we have proposed an approach of negotiation protocol for services agreement between two wireless nodes in ad hoc networks. Protocol principles are based on peculiarities of mobile nodes and mobile users on MANET, i.e., user autonomy, node functionality and resource management. Mobile users can use this negotiation protocol for defining its network functions in MANET based on their policy. Service level agreements between two wireless nodes can be renegotiated depending on current user's application requirements and available resources. Protocol is designed to be able to negotiate on many parameters such as route, link bandwidth or QoS. We also present a scenario in MANET to show the effectiveness of our proposed protocol. © 2005 IEEE.
