Sensor networks differ from traditional networks in several ways: sensor networks have
severe energy constraints, redundant low-rate data, and many-to-one flows. The end-to-end …

In-network data aggregation is essential for wireless sensor networks where energy
resources are limited. In a previously proposed data dissemination scheme (directed …

We propose the use of multiple gateways to significantly reduce latency and energy
consumption in multi-hop wireless sensor networks during data aggregation. We have …

There has been a growing interest in the applications of sensor networks. Since sensors are
generally constrained in on-board energy supply, efficient management of the network is …

A fundamental challenge in the design of Wireless Sensor Networks (WSNs) is to maximize
their lifetimes especially when they have a limited and non-replenishable energy supply. To …

A network of sensors can be used to obtain state-based data from the area in which they are
deployed. To reduce costs, the data, sent via intermediate sensors to a sink, are often …

This paper considers the problem of minimizing the amount of communication needed to
send readings from a set of sensors to a single destination in energy constrained wireless …

A fundamental challenge in the design of wireless sensor networks (WSNs) is to maximize
their lifetimes. Data aggregation has emerged as a basic approach in WSNs in order to …

This paper presents TiNA, a scheme for minimizing energy consumption in sensor networks
by exploiting end-user tolerance to temporal coherency. TiNA utilizes temporal coherency …
