Sensors combined with latest technologies can facilitate the dream of connecting everything in our daily lives to a network of devices easily. There is need for a middleware which can interconnect wireless sensors seamlessly with minimum software and hardware requirements. Previous work is restricted because it has only concentrated on one aspect which is application specific middleware. We propose a novel framework that allows the user to register events as well as query the system directly or through storage service. In this paper we are introducing a novel idea of storing data with in the sensor network for the life time of ad hoc wireless sensor networks (WSN). Previous works have used temporary storage but we implement persistent storage that provides increased functionality. This would help in saving precious resources like battery life by only extracting processed data which means less data would be sent to the users. Storing the data with in the network serves two purposes. First, it would help in further processing of the data for example to create implicit relationships between data and second it saves energy because transmission consumes more energy. The persistent storage will not only provide data consistency at all times by having multiple synchronised copies but also the facility to add context. The copies will be synchronised by sending data at the same time to all copies within the network after adding application required context through the data adaptation service.
