Mobile Cloud Computing has been worldwide accepted as a concept that can significantly improve the user experience when accessing mobile services. Mobile applications have become more popular all across the world. By removing the limitations of mobile devices with respect to storage and computing capabilities and providing new integrated levels of security by centralized maintenance of security-critical...
A clustering architecture increases network lifetime, fault tolerance and results in more efficient use of network resources. Mobile Ad-hoc Networks (MANETs) are extremely vulnerable to a variety of misbehaviors because of their basic features like: lack of communication infrastructure, dynamic network topology and short transmission range. To detect and reduce those misbehaviors, numerous trust management...
This paper provides on introduction on key strategy for wireless sensor network. Many key Strategy are focus on proposed pair wise based on key strategy technique. Key management Mechanism Provide a security over a Wireless sensor network. Many Scheme are focus on proposing new pair wise based key management strategy. The key management mechanism combines trusted-server and key pre-distribution scheme...
The ability to measure location using time of flight in 802.11 networks is impeded by the standard one microsecond clock resolution, imprecise synchronization of the 802.11 protocol, and the inaccuracy of available clock oscillators. We demonstrate a technique for off-the-shelf 802.11 hardware that enables accurate determination of location of transmitting 802.11 devices using time difference of arrival...
