Abstract: In wireless sensor networks, dynamic packet length control is more efficient in terms of channel utilization and energy efficiency. In previous packet length optimizations for sensor network often employ a fixed optimal packet length scheme, while dynamic packet length provide accurate radio link estimation and increase system throughput. The adaptation of dynamic packet length is 802.11 wireless system. The packet delivery ratio keeps high i.e. 95% above and link estimated error within 10% for 95% link. The experiments provide optimization of dynamic packet length achieves best performances related to the previous experiments.
