Although cellular networks such as GPRS (2.5G) or UMTS (3G) have achieved providing both circuit-switching and packet-switching services with wide area coverage, the mobile users are still expecting higher rates and more mobility to satisfy their needs. Integrating current network architecture with other high-speed and low-cost wireless technologies is a key challenge for migrating to 4G. The IEEE 802.11 technology which has been well-developed and widely-used in local area networks seems to be a proper choice for fulfilling users' expectations. Its ad hoc functionality further improves the mobility of the users. This research proposes an architecture to achieve the internetworking between 802.11 Mobile Ad Hoc Network (MANET) and UMTS. The key approach being applied for intersystem handovers is SGSN signaling and for ad hoc mobility management is the Mobile IP signaling. The main purpose of this research is to retrieve the best effects by integrating these two network technologies. The integration system results several important features: wide area coverage, mobility and quality of service management.

Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure. The nodes in MANET themselves are responsible for dynamically discovering other nodes to communicate. A number of challenges like open peer-to-peer network architecture, stringent resource constraints, shared wireless medium, dynamic network topology etc. are posed in MANET. In this research, we identify the existent security threats an ad hoc network faces, the security services required to be achieved and the countermeasures for attacks in each layer. To accomplish our goal, we have done literature survey in gathering information related to various types of attacks and solutions, as well as we have made comparative study to address the threats in different layers. Finally, we have identified the challenges and proposed solutions to overcome them. There is no general algorithm that suits well against the most commonly known attacks such as wormhole, rushing attack, etc.

Mobile Ad Hoc Network (MANET) is a collection of communication devices or nodes that wish to communicate without any fixed infrastructure and pre-determined organization of available links. The nodes in MANET themselves are responsible for dynamically discovering other nodes to communicate. Although the ongoing trend is to adopt ad hoc networks for commercial uses due to the property of its capability in forming temporary network without the aid of any established infrastructure or centralized administration. Due to this unique property, the main challenge is the vulnerability to security attacks. A number of challenges like open peer-to-peer network architecture, stringent resource constraints, shared wireless medium, dynamic network topology etc. are posed in MANET. As MANET is quickly spreading for, security challenges has become a primary concern to provide secure communication. In this paper, we identify the existent security threats an ad hoc network faces, the security services required to be achieved and the countermeasures for attacks in each layer. To accomplish our goal, we have done literature survey in gathering information related to various types of attacks and solutions, as well as we have identified the challenges and proposed solutions to overcome them. In conclusion, we focus on the findings and future works which may be interesting for the researchers like robust key management, trust based systems, data security in different layer etc. However, in short, we can say that the complete security solution requires the prevention, detection and reaction mechanisms applied in MANET.

Device-to-Device (D2D) is one of the emerging technologies expected to have significant contributions to the future of the Internet. The combination of personal mobile devices and D2D communications forms the Mobile Ad-hoc Network architecture, called MANETs. Nowadays, due to the flexibility and simplicity of establishing data transmission, MANETs are applied in various areas such as healthcare, intelligent transportation systems, tactical, smart retail, and smart agriculture. In practice, due to the mobility of network nodes, the network structure often changes, and the performance of MANETs is relatively low. Routing is one of the significant challenges of MANETs. In this study, we perform a comprehensive analysis of the traditional routing protocols for MANETs. Based on the analysis results, we obtained a common framework for designing routing protocols for MANETs. To visualize the efficiencies of protocols under variable network traffic, we performed a simulation to compare the performance of typical protocols, including AODV, DSR, and OLSR. The obtained results again demonstrated that on-demand-based routing protocols are suitable for dynamic topology networks. We hope that this work will be an essential guide in researching and proposing energy-saving, secure, and QoS routing protocols for MANETs in the future.

Efficient and reliable mobile interconnect protocol lays foundation for rapidly mobile networking of wireless Ad hoc network. Aimed at the contradiction between the requirements of practical application and the mobile IP protocol of Hierarchical Distributed Mobile Ad hoc Network (HD-MANET) in existence, one mobile interconnect protocol for HD-MANET was proposed based on the abstracted hierarchical distributed network configuration, which binds the commonness of mobile interconnect and the individuality of HD-MANET networking, so it can meet the application requirements of typical HD-MANET. Simulation experiment based on OPNET verified that the hierarchical distributed mobile interconnect protocol can greatly decrease network overhead and shorten the average time for node switching.
