Design and implementation of quality of service and security in group Communication over mobile Adhoc networks

Abstract

Mobile Adhoc Network MANET is an autonomous collection of newlinemobile nodes that communicate over relatively bandwidth constrained newlinewireless links Since MANETs require no existing communication newlineinfrastructure, they offer significant advantages in their scalability and newlineflexibility These attributes make MANETs extremely attractive for newlinespecialized application environments such as those encountered on the newlinebattlefield in emergency situations and in disaster areas newlineMANETs also exhibit significant weaknesses in security and newlineproviding QoS on demand for media streaming applications when compared newlineto other wireless communication solutions An analysis of QoS factors in newlineMANET for multimedia protocols such as RTP Real Time Protocol RTCP newlineReal Time Control Protocol RTSP Real Time Streaming Protocol and newlineMGCP Media Gateway Control Protocol newline
