Wireless sensors in network work with each other to sense some physical phenomenon and then the information gathered is processed to get relevant results. Reprogramming protocols are based on centralized approach. If base station is affected at any causes the whole process will be failed. To overcome this problem, Secure and Distributed Reprogramming Protocol (SDRP) is used. In distributed reprogramming mechanism multiple authorized network users can simultaneously and directly reprogram sensors nodes without the involvement of base station.
