Emergence of latest technologies has diverted the focus of people form Computer-Supported Collaborative Learning (CSCL) to mobile supported collaborative learning. MCL is highly demanded in educational organizations to substantiate the pedagogical activities. Some of the MCL supportive architectures including applications are introduced in several fields to improve the activities of those organizations, but they need more concise paradigm to support both types of collaboration: synchronous and asynchronous. This paper introduces the new preusability testing method that provides educational support and gives complete picture for developing new pedagogical group application for MCL. The feature of application includes asynchronous and synchronous collaboration support. To validate the features of application, we conduct the post usability testing and heuristic evaluation, which helps in collecting the empirical data to prove the effectiveness and suitability of Group application. Further, application aims to improve learning impact and educate people at anytime and anywhere.

Mobile collaborative learning (MCL) is extensively recognized field all over the world. It demonstrates the cerebral approach combining the several technology to handle the problem of learning. MCL motivates the social and educational activities for creating healthier environment. To advance and promote the baseline of MCL, different frameworks have been introduced for MCL. From other side, there is no highly acceptable security mechanism has been implemented to protect MCL environment. This paper introduces the issue of rogue DHCP server, which highly affects the performance of users who communicate with each other through MCL. The rogue DHCP is unofficial server that gives incorrect IP address to user in order to use the legal sources of different servers by sniffing the traffic. The contribution focuses to maintain the privacy of users and enhances the confidentiality. The paper introduces multi-frame signature-cum anomaly-based intrusion detection systems (MSAIDS) supported with innovative algorithms, modification in the existing rules of IDS and use of mathematical model. The major objectives of research are to identify the malicious attacks created by rogue DHCP server. This innovative mechanism emphasizes the security for users in order to communicate freely. It also protects network from illegitimate involvement of intruders. Finally, the paper validates the mechanism using three types of simulations: testbed, discrete simulation in C++ and ns2. On the basis of findings, the efficiency of proposed mechanism has been compared with other well-known techniques.

The rogue DHCP is unauthorized server that releases the incorrect IP address to users and sniffs the traffic illegally. The contribution specially provides privacy to users and enhances the security aspects of mobile supported collaborative framework (MSCF) explained in [24].The paper introduces multi-frame signature-cum anomaly-based intrusion detection systems (MSAIDS) supported with novel algorithms and inclusion of new rules in existing IDS. The major target of contribution is to detect the malicious attacks and blocks the illegal activities of rogue DHCP server. This innovative security mechanism reinforces the confidence of users, protects network from illicit intervention and restore the privacy of users. Finally, the paper validates the idea through simulation and compares the findings with known existing techniques.

Mobile collaborative learning (MCL) is highly acknowledged and focusing paradigm in eductional institutions and several organizations across the world. It exhibits intellectual synergy of various combined minds to handle the problem and stimulate the social activity of mutual understanding. To improve and foster the baseline of MCL, several supporting architectures, frameworks including number of the mobile applications have been introduced. Limited research was reported that particularly focuses to enhance the security of those pardigms and provide secure MCL to users. The paper handles the issue of rogue DHCP server that affects and disrupts the network resources during the MCL. The rogue DHCP is unauthorized server that releases the incorrect IP address to users and sniffs the traffic illegally. The contribution specially provides the privacy to users and enhances the security aspects of mobile supported collaborative framework (MSCF). The paper introduces multi-frame signature-cum anomaly-based intrusion detection systems (MSAIDS) supported with novel algorithms through addition of new rules in IDS and mathematcal model. The major target of contribution is to detect the malicious attacks and blocks the illegal activities of rogue DHCP server. This innovative security mechanism reinforces the confidence of users, protects network from illicit intervention and restore the privacy of users. Finally, the paper validates the idea through simulation and compares the findings with other existing techniques.
