Reliable data transmission in wireless sensor network plays a critical part with the
presence of increased data traffic and congestion. Successful data transmission can be
ensured by providing cache resources to store the data before transmission. Reliable Transport
protocol with a cache aware congestion control mechanism (RT-CaCC) is the existing
approach used for secured communication. However, in this existing works, cache resource
allocation is done evenly to all data flows on network which lead to data transmission failure
due to insufficient resources. Cache resource allocation should be performed evenly in order
to obtain consistent and successful data transmission. Priority based Cache Allocation and
Congestion Control protocol (P-CACC) is used in this work for effective cache resource
allocation. In the proposed research work, data transmission is performed reliably by giving
more prioritization to the data flow with higher data rate. Here, initially uneven cache
partitioning scheme is introduced for giving more prioritization to the flow with higher data
rates. This is done by measuring the priority of the multiple data flows present in the network,
and the weight assignment is done with the assistance of cuckoo search algorithm where the
data flow with more priority will be assigned with more weight. The higher cache partition will
be allocated to the data flow assigned with higher weight value. The simulation of the work is
performed in NS2. It is confirmed that proposed research work tends to have improved
outcomes than the existing techniques.
