- On the Separation of Channel and Network Coding in Aref Networks
- In this paper it is shown that one cannot always layer, or separate, channel and network coding for multicasting in deterministic relay networks with no interference. The authors call such networks Aref networks. The suboptimality of such layering in Aref networks is in contrast to the optimality of a similar...

- Overlay Service Architecture for Mobile Ad-Hoc Networks
- Ad-hoc networks are an emerging technology with enormous potential. However, the lack of support for large-scale deployment of applications has hindered the adoption of these networks for commercial use. This paper addresses this shortcoming and details an architecture that supports largescale deployment of services in ad-hoc networks. A new class...

- Multiple-Copy Routing in Intermittently Connected Mobile Networks
- Intermittently connected mobile networks are wireless networks where most of the time there does not exist a complete path from the source to the destination. There are many real networks that fall into this paradigm, for example, wildlife tracking sensor networks, military networks, inter-planetary networks, etc. In this context, conventional...

- Connecting Wireless Sensornets With TCP/IP Networks
- Wireless sensor networks are based on the collaborative efforts of many small wireless sensor nodes, which collectively are able to form networks through which sensor information can be gathered. Such networks usually cannot operate in complete isolation, but must be connected to an external network through which monitoring and controlling...

- Capacity Bounds for Relay Networks
- Recently developed PdE outer bounds on the capacity region of classical networks are extended to networks with broadcasting, interference, and noise. Examples demonstrate that the new bounds improve on cut-set bounds. In this paper, the authors generalize the applicability of PdE bounds to networks other than classical networks. The authors...

- Surveying Wireless Networks
- Wireless networks are a useful complement to a wired network, allowing network connections to be obtained anywhere within an area rather than only at fixed network connection points. However, wireless networks suffer from a number of problems that do not affect wired networks; in particular that the medium they use...

- Blacklist-Aided Forwarding in Static Multihop Wireless Networks
- Static broadband wireless networks, due to their ease of deployment, are likely to proliferate in the near future. The major stumbling block, however, is that wireless links are prone to external interference, channel fading, inclement weather, etc. Therefore scalable and reliable routing despite frequent link quality fluctuations is needed for...
