Mobile adhoc networks require stronger privacy protection due to the open nature of their media. Schemes such as AODV, ANODR, ALARM uses either one time or long term public key cryptosystems or combination of both achieving only partial anonymity and unobservability. Also, these schemes depend on public key cryptography and hence incurring high computation overhead. Our proposed technique overcomes these disadvantages by employing group signature and ID based encryption together instead of Public Key Cryptosystem. This scheme is thought to offer complete unobservability of both types. Our...

Future Wireless systems will be characterized by their heterogeneity. Multiple access technologies provide access to internet content.Vertical handoff is an important mechanism for achieving continuous seamless transmissions in these networks. When connections need to migrate between heterogeneous networks seamless vertical handoff is necessary. Hence seamless vertical handoff is the first step. With regard to VHO performance, there is a critical need to develop algorithms for connection management and optimal resource allocation for seamless mobility. The integration of WLAN and Wimax has...

Mobile Ad-hoc Network is an infrastructure less and decentralized network which needs a robust dynamic routing protocol. Many routing protocols have been proposed to accommodate the needs of communications for Mobile Adhoc Network. In this project, there is problem in delivering data packets for highly dynamic mobile ad hoc networks in a reliable and timely manner. Most existing ad hoc routing protocols are susceptible to node mobility, especially for large-scale networks. Driven by this issue, an efficient protocol was introduced. It takes advantage of the stateless property of geographic...
