A mobile wireless sensor network (MWSN) can simply be defined as a wireless sensor network (WSN) in which the sensor nodes are mobile. MWSNs are a smaller, emerging field of research in contrast to their well-established predecessor. MWSNs are much more versatile than static sensor networks as they can be deployed in any scenario and cope with rapid topology changes. However, many of their applications are similar, such as environment monitoring or surveillance. Commonly, the nodes consist of a radio transceiver and a microcontroller powered by a battery, as well as some kind of sensor for detecting light, heat, humidity, temperature, etc.

Methods and apparatus for global wireless sensor network architecture and protocol for remote supervision, asset control and operational management based on localized clusters of autonomous sensor / supervision / operational sensor nodes capable of ad hoc interconnection with nearby nodes and connection to gateway nodes with increased network functionality. These localized cluster nodes send data to gateway nodes either directly or through multi-hop transactions. The gateway nodes are, in turn, connected to other gateway nodes and operations control centers either through wireless or wired data communications links. Utilizing the Internet for long range interconnectivity, the network is scaleable to a global level. The resulting network is based on an ad hoc mesh topology to allow flexibility in network modification and expansion and is comprised of a tiered structure defined by increasing functionality. A current application for this technology is the remote control and supervision of lighting systems for facilities and municipalities on a local, national and / or global basis from centralized regional operations centers.

A scalable, minimum node complexity, energy efficient, and error-resilient routing method for wireless sensor networks is described. The network is partitioned into regions by power controlled base station scans using a directional antenna. Routing is performed using only local location information and instructions received from the base station at each sensor node with minimum processing and control overhead, thus allowing simple, low-cost sensor designs. Sensors in the network provide to a base station reports of the condition of the sensors themselves, and these reports are analyzed by the base station to determine improved routing instructions, which are then provided to the sensor nodes in control messages. Each data packet is relayed in an interleaved, loop-free mesh of sectors toward the base station, making data delivery robust to sensor failures and transmission errors. The disclosure also contains descriptions for simple edge-based tasking, query, code distribution, and network programming for sensor nodes. The method is suitable for large-scale, dense sensor networks for detection, alarming, and monitoring applications.
