The Effect of Packets Length Management Strategies on the Efficiency of the MAC Level Packet in Switched Radio Networks


The paper studies a new method of efficiency enhancement of packet switched radio networks at the radio channel access level. To this end, we consider the known strategies of packet lengths control in such radio networks and reveal incompleteness of a possible set of packet lengths management with channel conditions under carrier sense multiple access (CSMA) protocol. We propose three new strategies to change packet lengths which complete the set. Mathematical simulation is conducted for persistent and nonpersistent CSMA protocols. The quantative data on the average data rate, channel throughput and stability limits are obtained for every new strategy. Furthermore, we compare new and known strategies and system parameters and outline their advantages as compared to the known ones. The proposed packet length management strategies can be used to improve efficiency of existing radio networks with competitive radio channel access as well as to design new ones.
