Abstract [en]

Strategic planning is a decisive process toward sustainable development for any organization. Mozambique has developed many tools toward good governance, among which Poverty Alleviation Strategy Paper (PARPA) is an umbrella. PARPA includes different key decisive segments of society, particularly the Information and Communication Technologies (ICTs) as the pool for development. This chapter investigates to what extent e-Governance, particularly the development of strategies based on ICTs, can contribute to minimize the impact of floods at local governments by addressing best practice and decision-making process. The authors address backcasting methodology as an approach to consider in a participatory strategic planning for long-term decision-making processes. They use Chókwe District as a showcase where e-governance has an impact in mitigating and preventing the impact of floods.

Abstract [en]

This paper maintains that mobile phone payments present a significant opportunity to integrate more users within Uganda's financial system. Besides enabling services that can improve the performance of small businesses, mobile payments afford an opportunity to integrate more users within the traditional banking system at a reasonable cost. In order to evolve a successful model and realise these benefits, Uganda can learn from the Philippines, a developing country with arguably the most successful and widespread use of mobile payments in the world. Action areas include reviewing the national policy and legal environment, building capacity and collaboration amongst multiple regulatory agencies, and the need to be accommodative of as many stakeholders as possible. This will create a truly national system that can leverage the projected growth of the mobile phone market and bring benefits to the general population.

Abstract [en]

The reconciliation of socially responsible (TCP) with irresponsible (UDP) network flows is the goal, while the idea behind the solution is to maintain the existing congestion management mechanisms for the former and to use the mobile agent paradigm to monitor and control the later ones. The comprehensive solution has been termed as Combined Model for Congestion Control (CM4CC) and elaborated in several articles. As responsive protocol, TCP controls the sending rates whenever there is an appearance of congestion. If a problem with UDP occurs, the model that incorporates seven different types of mobile agents takes over the sending rates of unresponsive flows and tames them down. The reaction is based on the information collected by monitoring agents that trigger the creation of control agents. Three types of agents are always present in the network, while the rest are created on as needed basis. CM4CC has been verified through a number of different network configurations and scenarios using the Optimized Network Engineering Tool (OPNET) simulation environment. The results suggest an encouraging solution to the problem of coexistence of responsive and non-responsive flows. It is crucial to the stability and performance of Internet today, where so many different applications and services run simultaneously.

Abstract [en]

TCP and UDP are the dominant transport protocols on the Internet. The first one is used for reliable transport, while the second one for multimedia applications. Their behavior is quite different, which makes coexistence a challenge. Namely, TCP is responsive to potential network problems, such as congestion, while UDP completely ignores it. The need to come up with a protocol that somehow extracts the �good: attributes of both TCP and UDP, and leaves out the less favorable to the Internet, has proved to be a challenging research venue. Rather then going for an �entirely� new protocol, our objectives have been to keep TCP as is, while using the mobile agent paradigm for UDP control. The proposed solution termed as Combined Model for Congestion Control (CM4CC) has been limited to wired networks. Today, the Internet is an aggregation of both wired and wireless infrastructures; the article focuses on the CM4CC extension in heterogeneous networks.

Abstract [en]

Despite the continuous developments concerning the performance of the global Internet, and hence networking in general, congestion management remains to be a significant challenge. This is due to the heterogeneity of (1) the infrastructure (wired and wireless), (2) network flows (responsive and unresponsive to congestion), and the enormous growth of users and the variety of services. There are number of solutions proposed to tackle congestion, especially concerning the co-existence of responsive and unresponsive transport protocols. One of those, termed as Combined Model for Congestion Control (CM4CC), in addition to the set of classical congestion control mechanisms employed by TCP, introduced mobile agents to manage the unresponsive flows, such as UDP. The paper goes beyond the theoretical foundations of CM4CC, established in a few early articles, by using the simulation paradigm to validate the model. In order to do so, various scenarios are implemented in the simulation environment provided by the Optimized Network Engineering Tool (OPNET). The results of the simulation study clearly prove that CM4CC, which is a collaborative effort by TCP feedback mechanisms and mobile agents monitoring and control of the network and in particular the behaviour of UDP sources, is more than a promising venue towards a comprehensive congestion management. Inter alia, the focus is on the extensions made to the OPNET to accommodate mobile agents beyond the multi-tier system, and thus extending the original simulation capacity to the areas such as congestion management, network performance enhancement and stability.
