Secure Scheduling for Cluster-based TDMA Schedule MAC in Wireless Sensor Network

The overwhelming application growth of wireless sensor network (WSN) evolved the performance requirement of WSN in terms of security. The WSN is susceptible to many different security attacks but security attacks on medium access control (MAC) layer are more disastrous because the main role of MAC layer is to allocate and manage the available resources. The main aim of the paper is to explore the possibility of attack on cluster based MAC and to propose the solution to reduce or avoid the effect of attack in case of cluster-based time division multiple access (TDMA) schedule MAC. The paper give proposal of the cluster head (CH) attack on cluster-based MAC which attack on CH and increase the chances of CH re-election by draining the energy of CH and introduce the inter- and intra-cluster collisions. To diminish the effect of CH-attack paper put forward the idea of Secure-Green Conflict Free (S-GCF) which assigns the secure slots to CH and decreases the effect of CH-attack. The S-GCF shows better energy consumption, throughput and delay than cluster based TDMA schedule MAC Green Conflict Free (GCF) algorithm under CH-attack.
