Abstract:

 Due to the availability of multiple sensing units o n a single radio board of the modern sensor motes, some sensor 
networks need to handle heterogeneous traffic withi n the same application. This diverse traffic could have different priorities 
in terms of transmission rate, required bandwidth, packet loss, etc. Because of the multi'hop transmission characteristic of 
this prioritized heterogeneous traffic, occurrence of congestion is very common and unless handled eff ectively, it could thwart 
the application objectives. To address this challen ge, in this paper we propose a Prioritized Heteroge neous Traffic'oriented 
Congestion Control Protocol (PHTCCP) which performs hop'by'hop rate adjustment controlling the congestion and ensures 
efficient rate for the prioritized diverse traffic. This protocol also could be applied for healthcare infrastructure. We exploit 
cross layer approach to perform the congestion cont rol. Our protocol uses intra'queue and inter'queue priorities along with 
weighted fair queuing for ensuring feasible transmi ssion rates of heterogeneous data. It also guarante es efficient link 
utilization by using dynamic transmission rate adju stment. We present detailed analysis and simulation results with the 
description of our protocol to demonstrate its effe ctiveness in handling prioritized heterogeneous tra ffic in Wireless Sensor 
Networks (WSNs).
