Bounds on the Energy Consumption of Routings in Wireless Sensor Networks
- 2003. - 1
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Energy is one of the most important resources in wireless sensor networks. We use an idealized mathematical model to study the impact of routing on energy consumption. Our results are very general and, within the assumptions listed in Section 2, apply to arbitrary topologies, routings and radio energy models. We find bounds on the minimal and maximal energy routings will consume, and use them to bound the lifetime of the network. The bounds are sharp, and can be achieved in many situations of interest. We illustrate the theory with some examples.

Bounds on the Lifetime of Wireless Sensor Networks

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Energy is one of the most important resources in wireless sensor networks. We use an idealized mathematical model to study the energy consumption under all possible routings. Our results are very general and, within the assumptions listed in Section 2, apply to arbitrary topologies, routings and radio energy models. We find bounds on the minimal and maximal energy routings will consume, and use them to bound the lifetime of the network. The bounds are sharp, and we show that they are achievable in many situations of interest. We give some examples, and apply the theory to the problem of covering a given square region with the most efficient member of a family of increasingly more dense square-lattice sensor networks. Finally, we use simulations to test these results in a more realistic scenario, where packet loss can occur.

SILK: Scout Paths in the Linux Kernel
- 2002
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- SILK stands for Scout In the Linux Kernel, and is a port of the Scout operating system to run as a Linux kernel module. SILK forms a replacement networking subsystem for standard Linux 2.4 kernels. Linux applications create and use Scout paths via the Linux socket interface with virtually no modifications to the applications themselves. SILK provides Linux applications with the benefits of Scout paths, including early packet demultiplexing, per-flow accounting of resources, and explicit scheduling of network processing. SILK also introduces the concept of an \emphextended path to provide a framework for application QoS. We demonstrate the utility of SILK by showing how it can provide QoS for the Apache Web server.

An integrated approach to developing sensor network solutions
- 2004. - 1
-
Ingår i: Proceedings of the Second International Workshop on Sensor and Actor Network Protocols and Applications.

Konferensbidrag (refereegranskat)abstract
- This paper describes a prototype sensor networking platform and its associated development environment. Key elements of the system are the ESB sensor hardware, the Contiki operating system, and the communication stack, which includes a MAC layer and a highly optimized TCP/IP. Because the work is driven by prototype applications being developed by project partners, particular attention is paid to the development environment and to practical deployment issues. Three prototype applications are also presented.

Connecting wireless sensornets with TCP/IP Networks
- 2004

Konferensbidrag (refereegranskat)abstract
- 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 entities can reach the sensornet. As TCP/IP, the Internet protocol suite, has become the de-facto standard for large-scale networking, it is interesting to be able to connect sensornets to TCP/IP networks. In this paper, we discuss three different ways to connect sensor networks with TCP/IP networks: proxy architectures, DTN overlays, and TCP/IP for sensor networks. We conclude that the methods are in some senses orthogonal and that combinations are possible, but that TCP/IP for sensor networks currently has a number of issues that require further research before TCP/IP can be a viable protocol family for sensor networking.
