In analytical studies of multi-hop wireless networks, the spatial distribution of transmitters is typically modeled using a homogeneous Poisson point process. In this article, we show how such a modeling is inaccurate and leads to an inappropriate interference distribution for CSMA/CA networks. We then study a more realistic model, the Matèrn point process, which still reveals some unexpected f...

Wireless Sensor Networks have some well known features such as low battery consumption, changing topology awareness, open environment, non reliable radio links, etc. In this paper, we investigate the benefits of Network Coding Wireless Sensor networking, especially resiliency. One of our main concern is the resiliency in Wireless Sensor Networks. We have seen that resiliency could be described ...

A computing infrastructure where " everything is a service " offers many new system and application possibilities. Among the main challenges, however, is the issue of service substitution for the application execution in such heterogeneous environments. An application would like to continue to execute even when a service disappears, or it would like to benefit from the environment by using bett...

Providing high data rate with minimum energy consumption is a crucial challenge for next generation wireless networks. This paper focuses on wireless mesh networks using a MAC layer based on S-TDMA (Spatial Time Division Multiple Access). We investigate on the optimization issues combining throughput and energy consumption. Our contributions are two-fold. First, we formulate and solve using col...
