Location Based Service Applications (LBSAs) are becoming a part of our lives. Through these applications the users can interact with the physical world and get all data they want.eg; Foursquare .But it misuses it in many ways by extracting personal information of users and lead to many threats. To improve the location privacy we use the technique LocX. Here, the location and data related with it are encrypted before store in different servers. So a third party cannot track the location from the server and the server itself cannot see the location. In addition, to improve the security in location points and data points we introduce dual encryption method in LocX. Asymmetric keys are used to encrypt the data with two keys public key and user's private key. But in LocX random inexpensive symmetric keys are used.

The Wireless Mesh Network (WMN) has become the focus of much research since they allow increased network coverage, low cost and easy deployment. WMN includes the Internet Gateways (IGW), mesh routers and mesh clients forming a three layer architecture. Throughput and fairness are major issues in WMN as the network needs to satisfy increasing network demands and must be fair to all the clients requesting the demand. The gateway may become a bottleneck as all the traffic in WMN is routed to and from the gateway. All these above factors affect the performance of network. Thus the scheduling and load-balancing have become main challenges in WMN. Several scheduling and load balancing schemes have been discussed in this paper. Two scheduling models explored are interference-based and tree-based. Four load balancing schemes discussed are path-based, gateway-based and mesh-router-based. General TermsWireless mesh networks (WMN), throughput, fairness.
