Priority Based Congestion Control Dynamic Clustering Protocol in Mobile Wireless Sensor Networks

Algorithm 1

Algorithm for processing packets in CM and CH node.

   (a) Algorithm for queue model in CM

Input: - incoming packet

Output: queue in which packet to be stored

Variables:

   -Lower queue threshold

    - Upper queue threshold

   - Current queue length

For each CM node

   For every packet to queue in

   Check the current queue length aginst and

         If

            Queue in both and , Queue act as FCFS

         Else if   &&  

            Queue in and drop randomly

         Else

            Drop both and

         Endif

   (b) Algorithm for queue model in CH

For each CH node

   Check the current queue length aginst and

         If

            Queue in at tail selectively,

            Queue in at the head

            Queue act as priority queue

         Else if   &&  

            Queue in selectively and drop randomly

         Else

            Drop both and

Endif End
