Energy awareness in heterogeneous networks

Energy awareness in heterogeneous networks
The concept of mesh networks brings many challenges to the research community when designing such a system. In addition, allowing the physical mobility of the nodes in the network makes matters even more complicated. The nature of the limited resources that each node has makes a more efficient communication of prime importance. In this research,...

Mobility and applications of ad hoc networks

Mobility and applications of ad hoc networks
Ad hoc networks, or networks without a central controller, or a base station. The ability of nodes in such a network to move freely and autonomously in a physical region brings several challenges: maintaining the connectivity while the nodes move, fulfilling the requirements (QoS) of the application for which the network is deployed, and physically...

Mitigating attacks using adaptive beamnulling antennas

Mitigating attacks using adaptive beamnulling antennas
In multihop ad hoc networks, a jammer can drastically disrupt the flow of information by intentionally interfering with links between a subset of nodes. The impact of such attacks can escalate when the jammer is moving. As a countermeasure for such attacks, adaptive beam-forming techniques can be employed for spatial filtering of the jamming signal....
