The MAC framework: Redefining MAC protocols for wireless sensor networks

Most current WSN MAC protocol implementations have multiple tasks to perform—deciding on correct timing, sending of packets, sending of acknowledgements, etc. However, as much of this is common to all MAC protocols, there is duplication of functionality, which leads to larger MAC protocol code size and therefore increasing numbers of bugs....

MAC protocols for wireless sensor networks and their evaluation

The advent of small, and cheap sensors provides a wide range of measuring options. By making these sensors operate wirelessly we can now measure more than ever. However, wireless operation also provides new challenges. For example, how can we make these wireless sensors communicate effectively, i.e. without all the sensors trying to talk at the...
