Mobile Ad Hoc Networks (MANETs) provide an attractive solution for networking in the situations where network infrastructure or service subscription is not available. Its usage can further be extended by enabling communications with external networks such as Internet or cellular networks through gateways. However, data access applications in MANETs suffer from dynamic network connections and restricted energy supplies. Since Mobile Ad-hoc Networks (MANET) is large with sparse nodes, the routing information becomes more complex and it consumes more power, cluster-based routing techniques are used to tackle such situations. The data access efficiency can be improved using cooperative caching technique, which allows the sharing and coordination of cached data among multiple nodes inside the clusters. . In this paper, it is decided to propose modified Energy Efficient Clustered Cooperative Caching DSR protocol (EECCCDSR) to achieve the performance parameter like packet delivery ratio, routing overhead, energy consumption and delay. Though CCCDSR protocol has achieved performance parameters like packet delivery ratio, delay and bandwidth delay product, energy consumption is more. So efficient clustering has been done to reduce the power consumption.Keywords

With the advent of technology, embedded systems play a major role in various fields. In early stages for shooting wildlife videos and photos, the photographers used to spend more time for a single shot. The major disadvantage is that the shot taken may not be the required shot, so the work and energy used may be wasted. To overcome the above mentioned problem the surveillance system method was introduced. This proposed system will rectify the above mentioned problems with high efficiency. The NOOBS software is used for interfacing the hardware components and python is used as coding language. The working of surveillance system is as follows, when the camera is said to be turned ON, it will keep recording the whole footage without any human touch. When the obstacles are detected by PIR sensor, the PI camera is turned ON and it is identified by LED. The obstacles are captured by the camera and the captured footage is taken from the fixed location. If the obstacle goes out of range, the camera goes to sleep mode, which results in saving the power.
