Book Description
Routing and clustering for wireless sensor networks (WSN) play a significant role for reliable and energy efficient data dissemination. Although these research areas attract a lot of interest lately, there is still no holistic approach that is able to meet the requirements and challenges of many different applications and network scenarios, like various network sizes and topologies, multiple mobile data sinks, or node failures. The main goal of this work is to demonstrate that machine learning is a practical approach to a range of complex distributed problems in WSNs. Showing this will open up new paths for development at all levels of the communication stack. To achieve this goal we present a robust, energy-efficient, and flexible data dissemination framework consisting of the routing protocol FROMS and the clustering protocol Clique. Both are based on reinforcement learning, and exhibit vital properties such as robustness against mobility, node and link failures, fast recovery after failures, very low control overhead and a wide variety of supported network scenarios and applications. Both protocols are fully distributed and have minimal communication overhead.

Book Description
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 dissemination protocol. We present a protocol for efficient and reliable data delivery to all sensor nodes in an energy-constrained, event-driven sensor network in which nodes are mobile or static. The new protocol, SPROID (Scalable Protocol for RObust Information Dissemination), identifies data generated by a unique tag, uses content tables for faster dissemination of information and guarantees reliable dissemination to all nodes in the network within a finite time. SPROID can be made to work with any kind of physical layer requirements, but we focus on the case of a single-channel broadcast medium. Simulations results show that SPROID achieves complete data dissemination in shorter time and with more energy efficiency than SPIN (sensor network protocols using information negotiation).

Book Description
Owing to numerous potential applications, wireless sensor networks have been attracting significant research effort recently. Wireless sensor networks are capable of carrying out surveillance missions for various applications in remote areas without human interventions. A wireless sensor network typically goes through a cycle of producing sensor data through distributed calibration or detection, collaboratively processing the produced sensor data, and then either storing the processed sensor data within the network for later retrieval or communicating it directly to a user. Therefore, two critical issues of wireless sensor networks are to efficiently generate sensor data to provide sensing coverage per application requirements and deliver generated data per user requests, referred to as coverage maintenance and data dissemination in the literature, respectively. Under various assumptions on sensor devices and applications, this thesis studies different schemes regarding various aspects such as energy conservation, scalability, load balancing, battery efficiency, adaptability to mobility, and robustness.
