16. Challenges and Limitations Reliable and Trust models should be provided for supporting the users’ desires to comply with the rules of protocol. Thus, it is important to take into consideration these requirements in the proposed mobile P2P protocol for the ensemble mobile environment to overcome the challenges especially the mobility and heterogeneity. 16

17. Conclusion The need for developing a middleware with an enhanced protocol for Android-based mobile devices is becoming real. 17
