Traditionally, reliable multicast protocols are deterministic in nature. It is precisely this determinism which tends to become their limiting factor when aiming at reliability and scalability, particularly in highly dynamic networks, e.g., ad hoc networks ...
We consider a cross-layer design of wireless ad-hoc networks. Traditional networking approaches optimize separately each of the three layers: physical layer, medium access and routing. This may lead to largely suboptimal network designs. In this work, we p ...
We consider the question of what performance metric to maximize when designing ad-hoc wireless network protocols such as routing or MAC. We focus on maximizing rates under battery lifetime and power constraints. Commonly used metrics are total capacity (in ...
Reasoning about the success of distributed computations in the face of node and communication failures is an ever hard issue. This is particularly true in highly dynamic ad hoc networks where communication between two nodes can often take place only via in ...
We address the problem of securing the route discovery in mobile ad hoc networks, proposing a light-weight yet robust routing protocol, the Distance- Vector Secure Routing Protocol (DV-SRP). DV-SRP discovers on-demand multiple routes, which are established ...
We consider the problem of how throughput in a wireless network with randomly located nodes scales as the number of users grows. Following the physical model of Gupta and Kumar, we show that randomly scattered nodes can achieve the optimal 1/sqrt(n) per-no ...
When striving for reliability, multicast protocols are most commonly designed as deterministic solutions. Such an approach seems to make the reasoning about reliability guarantees (traditionally binary "all-or-nothing"- like) in the face of packet losses a ...
Providing reliable group communication is an ever recurring issue in distributed settings. In mobile ad hoc networks, this issue becomes more significant since all nodes act as peers, while the issue gets even more challenging due to highly dynamic and unp ...
Reliable storage of data with concurrent read/write accesses (or query/update) is an ever recurring issue in distributed settings. In mobile ad hoc networks, the problem becomes even more challenging due to highly dynamic and unpredictable topology changes ...
