In this paper we propose a routing strategy for enabling publish-subscribe communication in
a sensor network. The approach is semi-probabilistic, in that it relies partly on the …

The publish/subscribe paradigm represents a large class of applications in sensor networks
as sensors are designed mainly to detect and notify upon events of interests. Thus, it is …

Existing publish/subscribe architectures for wireless sensors networks only support
stationary sensors interconnected with each other. They cannot handle mobile sensors or …

Rapidly increasing development and application areas of wireless sensor networks requires
the deployment of highly scalable and dynamic communications paradigms for coping with …

Protocols for sensor networks have traditionally been designed using the best effort delivery
model. However, there are many specific applications that need a reliable data …

We present two protocols one of which supports the publication by sensors in a sensor-
network of messages on a named topic, the other that allows sensors to subscribe to …

A network-wide broadcast service is often used for information dissemination in sensor
networks. Sensor networks are typically energy-constrained and prone to failures. In view of …

In recent years, due to the rapid decrease in the cost of micro electro mechanical systems,
compact operating systems and the changing requirements of the users are enforced the …

Applications that require fine-grain monitoring of physical environments subjected to critical
conditions, such as fire, leaking of toxic gases and explosions, pose a great challenge to …

Sensor networks are composed of a large number of densely deployed sensors/actuators.
Routing protocols are faced with the challenge of delivering data to sinks through multihop …
