Companies realized the importance of well managing their relationship with customers. Mobile telecommunication market is very competitive because customers are tending to move from one company to another easily. Mobile telecommunication companies should focus on specific programs and services to satisfy the existing customer needs and ensures their fidelity within the company and also to attract new customers in order to increase market value of the company. Telecommunication Companies are using data mining thus by business intelligence to understand their customers in a better way to retain. The Objective of Customer relationship Management is to provide the companies a model that facilitates to decide what kind of loyalty programs they should deliver to their clients who have different characteristics. Today companies use Customer Relationshi...

Operators are keen analyzing their CDR (call detail record) obtained over the past usage for predicting the behavior of their customers and their usage. The operators are willing to mine knowledge from real-world dataset which implies the pattern of user mentality on this changing world. To identify the usage of 2G and 3G services the classification models were trained using the data collected from PAKDD 2006 dataset. In order to obtain the prediction accuracy, the classifiers were evaluated using 10 folds cross validation. On comparing the results of the experiment, J48 performed more accurately and random tree consumed less time.

In wireless networks users expect to get access to the network security and to exchange information anytime and anywhere. The ad hoc wireless network consists of mobile networks which creates architecture for communication without the help of traditional fixed-position routers. Establishing strong routes and providing security are the main tasks in MANETs. Routing is the critical issue in the MANET and focus based on routing protocols such as Ad hoc On-demand Distance Routing Protocol (AODV), Dynamic Source Routing (DSR), Temporally Ordered Routing Algorithm (TORA) and Optimized Link State Routing (OLSR) are interesting due to their applications. OPNET is used to establish the simulations of these routing protocols the performance of the routing protocols is studied by selecting metrics. Metrics are used to select the best path for exchanging information from source to destination. Result show that AODV and TORA is suitable for larger networks while changing network topology with selected metrics.
