Abstract
Messaging is a basic service in sensornets. Yet the unique system and application properties of sensornets pose substantial challenges for the messaging design: Firstly, dynamic wireless links, constrained resources, and application diversity challenge the architecture and protocol design of sensornet messaging; Secondly, complex faults and large system scale introduce new challenges to the design of fault-tolerant protocols. The objective of this dissertation is to address the aforementioned challenges of sensornet messaging. Despite the extensive effort in studying sensornet messaging, the lack of a basic understanding of its essential components has been an obstacle for reliable, efficient, and reusable messaging services in sensornets. To address this problem, one task of this dissertation is to identify the basic components of sensornet messaging and to study the related algorithmic design issues. More specifically, we propose the messaging architecture SMA that consists of three components: traffic-adaptive link estimation and routing (TLR), application-adaptive structuring (AST), and application-adaptive scheduling (ASC). TLR deals with dynamic wireless links as well as the impact of application traffic patterns on
