The Worst-Case Capacity of Wireless Sensor Networks: The key application scenario of wireless sensor networks is data gathering: sensor nodes transmit data, possibly in a multi-hop fashion, to an information sink. The performance of sensor networks is thus characterized by the rate at which information can be aggregated to the sink. This paper derives the first scaling...; Tags: Network, Sensor, Association For Computing Machinery, Sensor Network, Wi-Fi, Wireless; White papers 2007-04-27
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...; Tags: Network, Wireless, Sensor Network, Tcp/Ip, Network Technology, Networking; White papers 2007-01-01
Distributed TCP Caching for Wireless Sensor Networks: Many applications of wireless sensor networks are useful only when connected to an external network. Previous research on transport layer protocols for sensor networks has focused on designing protocols specifically targeted for sensor networks. The deployment of TCP/IP in sensor networks would, however, enable direct connection between the sensor network...; Tags: Network, Sensor, TCP, Sensor Network, Tcp/Ip, Wi-Fi, Networking, Wireless; White papers 2007-01-01
An Investigation Into Intra-Vehicle Sensor Networks: Wireless sensor networks enable the development of distributed sensing applications atop tiny "Mote" computing platforms.

TCP Support for Sensor Networks: Communication between sensors and controlling entities at the edge or outside the sensor network is needed for reliable remote sensor node management and reprogramming. TCP would be useful for tasks, where reliable unicast is appropriate, but the high bit error rates in wireless sensor networks lead to energy inefficiencies reducing...; Tags: Network, Sensor, TCP, Sensor Network, Tcp/Ip, Networking; White papers 2006-12-02

GPS-Free Node Localization in Mobile Wireless Sensor Networks: An important problem in mobile ad-hoc wireless sensor networks is the localization of individual nodes, i.e., each node's awareness of its position relative to the network. This paper introduces a variant of this problem directional localization where each node must be aware of both its position and orientation relative to...; Tags: Mobile, Network, Localization, Sensor, Wireless, Sensor Network, GPS, Handhelds, Networking, Consumer Electronics, Personal Technology, Hardware; White papers 2006-06-25
Greedy Is Good: On Service Tree Placement for In-Network Stream Processing: This paper is concerned with reducing communication costs when executing distributed user tasks in a sensor network. This paper takes a service-oriented abstraction of sensor networks, where a user task is composed of a set of data processing modules called services with dependencies. Communications in sensor networks consume significant energy...; Tags: Goal, Sensor Network, Networking; White papers 2006-04-07
Multi-Criteria Routing in Wireless Sensor-Based Pervasive Environments: Wireless sensor networks are expected to be an integral part of any pervasive computing environment. This implies an ever-increasing need for efficient energy and resource management of both the sensor nodes, as well as the overall sensor network, in order to meet the expected quality of data and service requirements....; Tags: Network, Network Service, Environment, Sensor, Wireless, Sensor Network, Networking; White papers 2005-12-01
