Artykuł omawia rozwiązanie, jakim jest zrównoważone przypisanie UE (terminali użytkowników) będących w trybie idle (gdy dla UE nie ustanowiono połączenia RRC). Dzięki zrównoważonemu rozkładowi UE, urządzenia, które powracają do trybu Connected, będą dołączać do komórek na pożądanych warstwach. Rozwiązanie to zapobiega zarówno nierównemu rozmieszczeniu aktywnych użytkowników, jak i sytuacjom przeciążenia.

The article presents the solution – a balanced distribution of UEs in idle mode (there is no RRC connection established for a UE). Thanks to a balanced distribution in idle mode, the UEs which return to connected mode will already be attaching to cells on the desired layers. Thus, this solution prevents both an unequal distribution of active users as well as the overload situations.
Multi-hop networks, such as WSNs, become an object of increasing attention as an emerging technology which plays an important role for practical IoT applications. These multi-hop networks generally consist of mobile and small terminals with limited resources, which makes them vulnerable to various network status changes. Moreover, the limited nature of terminal resources available, especially in terms of battery capacity, is one of the most important issues to be addressed in order to prolong their operating time. In order to ensure efficient communications in such networks, much research has already been conducted, especially in the field of routing and transmission technologies. However, conventional approaches adopted in the routing field still suffer from the so-called energy hole problem, usually caused by unbalanced communication loads existing due to difficulties in adaptive route management. To address this issue, the present paper proposes a novel routing algorithm that utilizes ACO-inspired routing based on residual energy of terminals. Operational evaluation reveals its potential to ensure balanced energy consumption and to boost network performance.
