Abstract

A Mobile ad hoc network (MANET) is a collection of independent mobile nodes that are self organized and self configured. Routing in MANET is a critical issue due to mobility of node and openness of network, so an efficient routing protocol makes the MANET secure and reliable. UOSPR deals with the concept of anonymity, unlinkability and unobservability as well as uses BATMAN proactive routing in which every node has knowledge of best hop details instead of maintaining entire network topology. In UOSPR there is latency in data transmission if route is not found in the routing table at a particular time interval. We know that ad hoc network has limited battery power, but already half of the power used for security in USOR and UOSPR, remaining power has to be used efficiently for calculating routes and data transmission. For this purpose UOSHR is introduced by combining reactive (USOR) and Proactive (UOSPR) routing protocols. This technique eliminates latency in finding route, achieves fast and secure transmission of data. NS2 is used to implement and validate the effectiveness of the design.KeywordsAnonymityunlikabilityunobservabilityprivacyroutingBATMANUSOR
