Abstract:
This thesis aims to design an Interference and Priority aware Coexistence
(IPC) algorithm, namely IPC, to mitigate coexistence between multiple num bers of WBANs within each other transmission ranges and using a single
channel for communication. Two interference detection techniques are used
to estimate interference density in a region. The First interference detec tion technique consider mutual distance between WBANs and their sensors
nodes. Location based information is shared by each centralized coordinator
node in a WBAN. The second technique use SINR estimation to estimate
interference power received from neighboring WBANs. Wireless body area
network consists of a centralized coordinator to receive data from sensor
nodes on or inside the body of the subject in consideration. This algorithm
runs on the coordinator and consider: 1) Node’s priority to allocate quality
of service timeslot, 2) SINR received to detect interference, 3) Packet length
to allocate time required for transmission and 4) Density of WBANs within
a specified range of area. Moreover, WBANs are both static and mobile
at different times and random mobility is generated to calculate simulation
results. Simulation results show that proposed algorithm achieves higher
packet delivery rate, reuse factor and system throughput at lower delay per
packet and energy per bit per second.
