Energy-efficient collision-free medium access control for wireless sensor networks
TL;DR: The traffic-adaptive medium access protocol (TRAMA) is introduced for energy-efficient collision-free channel access in wireless sensor networks and is shown to be fair and correct, in that no idle node is an intended receiver and no receiver suffers collisions.

Method and apparatus for providing mobile and other intermittent connectivity in a computing environment
TL;DR: In this article, a Mobility Management Server coupled to the mobile network maintains the state of any number of mobile end systems and handles the complex session management required to maintain persistent connections to the network and to other peer processes.

Improving wireless sensor network lifetime through power aware organization
Mihaela Cardei,Ding-Zhu Du +1 more
TL;DR: This paper proposes an efficient method to extend the sensor network operational time by organizing the sensors into a maximal number of disjoint set covers that are activated successively, and designs a heuristic that computes the sets.
Proceedings ArticleDOI
Impact of radio irregularity on wireless sensor networks
TL;DR: The RIM model is the first to bridge the discrepancy between spherical radio models used by simulators and the physical reality of radio signals, and shows that radio irregularity has a significant impact on routing protocols, but a relatively small impact on MAC protocols.
Journal ArticleDOI
In-network aggregation techniques for wireless sensor networks: a survey
TL;DR: A comprehensive review of the existing literature on techniques and protocols for in-network aggregation in wireless sensor networks is provided, and suitable criteria to classify existing solutions are defined.
