A wireless sensor network is an embedded computer network formed by small cheap devices, prone to errors. Communication in such a network in a single-hop range is provided by a Medium Access Control (MAC) Protocol. Chess has developed one such a MAC protocol, Gossip-MAC (G-MAC), specifically designed to service gossiping-based traffic. G-MAC was...

This study describes a method of implementing a fully integrated ultra-low-power (ULP) radio for wireless sensor networks (WSNs). This is achieved using an ad hoc modulation scheme (impulse radio), with a bandwidth of 17.7 MHz in the 2.4 GHz-ISM band and a specific medium access control (MAC) protocol, based on a duty-cycled wake-up radio and a...

Brouwers, N. (author)
Writing software for Wireless Sensor Networks (WSN) is hard, as programmers have to write robust, distributed, highly concurrent applications on extremely resource limited devices. Virtual machines offer among other things support for high-level object-oriented languages, dynamic memory management and protection, hardware abstraction, and...

Wireless sensor networks are becoming increasingly popular due to their low cost and wide applicability to support a large number of diverse application areas. Localization of sensor nodes is a fundamental requirement that makes the sensor data meaningful. Energy and cost constraints only allow to equip a few nodes with a GPS device and to...

In the development of wireless sensor networks, the lifetime of a sensor node is always a key design consideration. Since the battery in a sensor node can usually not be recharged or changed, power management is an effective way to extend the network lifetime. The wireless transceiver, also regarded as the ‘main radio’, is a relatively power...

Broadcasting by flooding is one of the most fundamental services for both wired and wireless networks. This also includes several sensor network applications that use broadcasting to spread information from one sensor node to the other sensor nodes in the entire sensor network. These wireless sensor networks have certain characteristics such as...

Li, S. (author)
When a sensor network is deployed, we fundamentally care about three main outcomes: to obtain as much data as possible (high delivery rate), to obtain data as fast as possible (low latency), and to obtain data for as long as possible (long lifetime). This last metric, called network lifetime, is of great importance and has been widely...

Software-Defined Networking (SDN) potentially can improve the flexibility and management of Wireless Sensor Networks (WSNs). To investigate the impact of SDN on WSN, in this thesis, we consider three Software-Defined Wireless Sensor Network (SD-WSN) frameworks, namely SDN-WISE, SDWN-ONOS, and TinySDN. After comparing these frameworks, the...
