Capacity scaling in delay tolerant networks with heterogeneous mobile nodes
We provide a general framework for the analysis of the capacity scaling properties in mobile ad-hoc networks with heterogeneous nodes and spatial inhomogeneities. Existing analyti...

A random perturbation-based scheme for pairwise key establishment in sensor networks
A prerequisite for secure communications between two sensor nodes is that these nodes exclusively share a pairwise key. Although numerous pairwise key establishment (PKE) schemes ...

Distributed opportunistic scheduling for ad-hoc communications: an optimal stopping approach
We consider distributed opportunistic scheduling (DOS) in wireless ad-hoc networks, where many links contend for the same channel using random access. In such networks, distribute...

Surviving attacks on disruption-tolerant networks without authentication
Disruption-Tolerant Networks (DTNs) deliver data in network environments composed of intermittently connected nodes. Just as in traditional networks, malicious nodes within a DTN ...

Scalable routing in delay tolerant networks
The non-existence of an end-to-end path poses a challenge in adapting the traditional routing algorithms to delay tolerant networks (DTNs). Previous works include centralized rout...

On exploiting asymmetric wireless links via one-way estimation
A substantial percentage of links in wireless networks, especially low-power ones, is asymmetric. For the low-quality direction of asymmetric links, we observe based on testbed ex...

Capacity of multi-channel wireless networks with random (c, f) assignment
The issue of transport capacity of a randomly deployed wireless network under random (c, f ) channel assignment was considered by us in [1]. We showed in [1] that when the number ...

Secure incentives for commercial ad dissemination in vehicular networks
Vehicular ad hoc networks (VANETs) are envisioned to provide us with numerous interesting services in the near future. One of the most promising applications is the dissemination ...
