Future networks are expected to become more complex and dynamic than today's networks. A centralized approach for network management is not able to deal with such complexity and dynamics, and will then introduce scalability problems. The concept of In Network Management (INM), where each INM entity (a network node) has the autonomy to self-govern its behavior, is being researched as an alternative...
A flexible Wireless Sensor Network platform for easier implementation of diverse applications has been developed and deployed at one of the Institute Superior Tecnico - Technical University of Lisbon (IST-TUL) campus. Since its initial deployment in 2007, this test-bed has grown steadily, supporting new nodes, applications and experiments. However, some initial problems, which were solved on an ad...
In wireless ad hoc networks, IEEE 802.11 power management may completely fail if power-saving (PS for short) stations are out of synchronization. To fix this problem, proposed various cyclic quorum-based power management (CQPM) protocols, which, however, may also completely fail if some PS stations have different schedule repetition intervals (SRIs). To conquer all these problems, we propose the OAPM...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
