Abstract: Heterogeneous Wireless Sensor Network (HWSN) consists of sensor nodes with different ability such as different computing power and sensing range. The networks have a wide range of applications and they are prone to security threats and they do have a wide range of applications like military, environmental monitoring, health care, etc., traditional network security methods are not up to the mark due to limited resources. In this study, the energy efficient and security based Hybrid Transmission Technique with Security (HTTS) is proposed for HWSN to solve above issues. Initially, the clusters are created by using the formation of sensor nodes, which are have a Cluster-Head (CH) that are used to performs data aggregation in the clusters sensor nodes then the aggregated data transmitting from multiple hops to the base station and this process reduces the bandwidth by eliminating the redundant data in a cluster. Then the energy efficient protocol called Hybrid Transmission Protocol (HTP) proposed for reduced the issues of limited power on mobile nodes. Second, the performance of a Cooperative Modulation Diversity (CMD) technique is evaluated. Finally, a key distribution scheme based on random key pre-distribution proposed for heterogeneous sensor networks to achieve better security and performance.
