Abstract

WSN is first choice of mission-critical applications such as navigation system, military, monitoring, industrial application and health sectors also. Larger demand makes it more prone to malicious attacks. Jamming attack is one of the malicious attacks which occupy the sensor by emitting larger bandwidth frequency. Thus jamming attack can manipulate the sensor according to its poisonous will i.e. to delay message broadcast in emergency situation and also degrade the throughput of WSN. In mission-critical situation message broadcast is must to avoid accident, e.g. navigation system and message alert situation. In order to disseminate the message efficiently, spread spectrum technique can be used because it can handle powerful jammer. Drawback of using it is that there is wastage of crucial bandwidth because to data it uses vast frequency band as compared to sending data frequency. To compensate this drawback, we merge mobile agent(MA) technique to spread spectrum(SS) technique to efficiently save the energy.MA technique by comparing assigned threshold value to nodes, can detect the jammed node and send alert message to base station and then base station accordingly take the action. In this paper, we will evaluate the merits and demerits using this integrated approach with SS and MA technique.
